Recently I tried setting up my own email server with the help of Luke Smith's
emailwiz script. And it went well.
echo "YUBha3RzYm90LmluCg==" | base64 --decode in your terminal, to hit me up
on the new email adress :)
Now I needed to use an email client with which I can connect to the mail server. I tried thunderbird, but it felt a bit too sluggish for my taste. Then I came across one of Luke Smith's other gems called mutt-wizard. Instead of running the tool he provided, I thought it'd be fun to set things up by hand. Hence this write-up.
Please watch this and this to get a feel for what we're going to be setting up.
Offlineimap when configured, will go to our email server and download all of our email to a folder of our choosing, on our computer.
Run the following to install it, if you're running voidlinux.
$ sudo xbps-install offlineimap
All the packages in this post are available in most distros. So consult your package manager docs on how to search for them.
To configure it, create a file called
.offlineimaprc in our
$ cat ~/.offlineimaprc [general] ui = ttyui accounts = mydomain.com,disroot.org #### account 1 ------------------------------------ [Account mydomain.com] localrepository = mydomain.com-local remoterepository = mydomain.com-remote [Repository mydomain.com-local] type = Maildir localfolders = ~/Mail/mydomain.com restoreatime = no [Repository mydomain.com-remote] type = IMAP remoteuser = yoshi remotepass = mySuperS3cr3tPassword remotehost = mail.mydomain.com ssl = yes sslcacertfile = /etc/ssl/certs/ca-certificates.crt #### account 2 ------------------------------------ [Account disroot.org] localrepository = disroot.org-local remoterepository = disroot.org-remote [Repository disroot.org-local] type = Maildir localfolders = ~/Mail/disroot.org restoreatime = no [Repository disroot.org-remote] type = IMAP remoteuser = email@example.com remotepass = mySuperS3cr3tPassword remotehost = disroot.org remoteport = 993
As we can see, we have 2 email accounts configured in the above config file.
mydomain.com is an example of an account created with the
What we're telling
offlineimap to do here is, to use details mentioned in
[Repository mydomain.com-remote] to fetch the emails and put them in a folder
[Repository mydomain.com-local]. The email would be downloaded to
disroot.org is an example of a disroot.org email account.
Its config is pretty much the same as
mydomain.com, except I had to specify connection
details like port number. Every mail provider has a common
settings page, so please refer
yours if errors show up.
Now when we run
$ offlineimap, it'll start downloading emails from
both our accounts to
~/Mail/disroot.org. It might
take a while to finish as it depends on the amount of mail we have.
If we just run
$ offlineimap -a mydomain.com or
$ offlineimap -a disroot.org,
it'll download email for just that account. The name should be the same as
what we mentioned in the
[Account xxxxx] section.
The next time we run
$ offlineimap, only new emails would get downloaded. And that's it
Go ahead and check your
msmtp, simply put is a tool for sending emails from the command-line.
Run the following to install it.
$ sudo xbps-install msmtp
When configured, we could do
$ echo "Subject: Oye from msmtp" | msmtp -a disroot.org firstname.lastname@example.org
email@example.com would get a mail from the account we configured with the
disroot.org. If this seems too weird, don't worry. It'll become a lot
clearer after we configure it.
Go ahead and create a file called
.msmtprc in our
$ cat ~/.msmtprc defaults protocol smtp auth on tls on tls_trust_file /etc/ssl/certs/ca-certificates.crt syslog LOG_USER logfile ~/.msmtp.log timeout 60 #### account 1 ------------------------------------ account mydomain.com host mail.mydomain.com port 587 domain mydomain.com from firstname.lastname@example.org user yoshi password mySuperS3cr3tPassword #### account 2 ------------------------------------ account disroot.org host disroot.org port 587 domain disroot.org from email@example.com user firstname.lastname@example.org password mySuperS3cr3tPassword account default : mydomain.com
offlineimap's config, we have sectioned the config based on the accounts
we'll be using. Pay attention to the
user line in both
For an email service like disroot, the username would be the full email address.
But for our email server, it'd be just a
With this in place, if we do
$ echo "Subject: Hello from msmtp" | msmtp -a mydomain.com email@example.com
firstname.lastname@example.org would receive a mail from our account in
disroot.org in the command above and we can send emails
using our account on disroot.
The last line in the config, just makes
mydomain.com as the default account, we'd
like to use, if none is provided as an argument. For example,
$ echo "Subject: Ola from msmtp" | msmtp email@example.com
would send a mail using the
mydomain.com account. And with that
msmtp is configured.
mutt is our mail client.
It can do both fetching and sending emails,
but configuring it for doing that for multiple accounts is notoriously painful.
Hence this approach.
Install it with
$ sudo xbps-install neomutt
In this writeup, we'll focus on making
msmtp, based on the account folder we're viewing.
To make things a bit more manageable, we'll be splitting up the config into multiple files.
The configs live in
~/.config/neomutt. So make sure that folder is present.
Let's start by setting up our different accounts first.
We need to be in
neomutt's config folder, so
$ cd ~/.config/neomutt.
$ mkdir accounts $ touch accounts/mydomain.com $ touch accounts/disroot.org
Now lets add content to those files.
$ cat accounts/mydomain.com unmailboxes * set from = "firstname.lastname@example.org" set sendmail = "/usr/bin/msmtp -a mydomain.com" set folder = "~/Mail/mydomain.com/" set spoolfile = "+INBOX" set postponed = "+Drafts" set record = "+Sent" set trash = "+Junk" alias me "Yoshi Nakamura" "email@example.com" set mbox_type = Maildir set ssl_starttls = yes set ssl_force_tls = yes mailboxes =INBOX =Sent =Drafts =Junk
neomutt comes with a sidebar to display the folders we have available in
a particular account. Later on in the config, we'd setup a keybind to toggle
unmailboxes * would just update the sidebar with the particular
account's folders, as we change between them. The rest of the config is pretty much
$ cat accounts/disroot.org unmailboxes * set from = "firstname.lastname@example.org" set sendmail = "/usr/bin/msmtp -a disroot.org" set folder = "~/Mail/disroot.org/" set spoolfile = "+INBOX" set postponed = "+Drafts" set record = "+Sent" set trash = "+Junk" alias me "Ou Rname" "email@example.com" set mbox_type = Maildir set ssl_starttls = yes set ssl_force_tls = yes mailboxes =INBOX =Sent =Drafts =Junk =Trash =Archive
To know, what are all the possible folder names we can set for
mailboxes, look inside
Now that we have both accounts setup, lets setup a way to toggle between them.
Create a file in neomutt's config folder called
$ cat mailboxes.muttrc macro index,pager <f2> '<sync-mailbox><enter-command>source ~/.config/neomutt/accounts/mydomain.com<enter><change-folder>!<enter>;<check-stats>' macro index,pager <f3> '<sync-mailbox><enter-command>source ~/.config/neomutt/accounts/disroot.org<enter><change-folder>!<enter>;<check-stats>' source ~/.config/neomutt/accounts/mydomain.com
All this file does is, when in neomutt, if we press
F3 we can switch
between our accounts. And by default the mail from
mydomain.com will be shown,
neomutt opens up.
By default, neomutt looks a bit plain, so lets add some colors to it. Create a
$ cat colors.muttrc # Default index colors: color index yellow default '.*' color index_author red default '.*' color index_number blue default color index_subject cyan default '.*' # New mail is boldened: color index brightyellow black "~N" color index_author brightred black "~N" color index_subject brightcyan black "~N" # Tagged mail is highlighted: color index brightyellow blue "~T" color index_author brightred blue "~T" color index_subject brightcyan blue "~T" # Other colors and aesthetic settings: mono bold bold mono underline underline mono indicator reverse mono error bold color normal default default color indicator brightblack white color sidebar_highlight red default color sidebar_divider brightblack black color sidebar_flagged red black color sidebar_new green black color normal brightyellow default color error red default color tilde black default color message cyan default color markers red white color attachment white default color search brightmagenta default color status brightyellow black color hdrdefault brightgreen default color quoted green default color quoted1 blue default color quoted2 cyan default color quoted3 yellow default color quoted4 red default color quoted5 brightred default color signature brightgreen default color bold black default color underline black default color normal default default # Regex highlighting: color header blue default ".*" color header brightmagenta default "^(From)" color header brightcyan default "^(Subject)" color header brightwhite default "^(CC|BCC)" color body brightred default "[\-\.+_a-zA-Z0-9]+@[\-\.a-zA-Z0-9]+" # Email addresses color body brightblue default "(https?|ftp)://[\-\.,/%~_:?&=\#a-zA-Z0-9]+" # URL color body green default "\`[^\`]*\`" # Green text between ` and ` color body brightblue default "^# \.*" # Headings as bold blue color body brightcyan default "^## \.*" # Subheadings as bold cyan color body brightgreen default "^### \.*" # Subsubheadings as bold green color body yellow default "^( | )*(-|\*) \.*" # List items as yellow color body brightcyan default "[;:][-o][)/(|]" # emoticons color body brightcyan default "[;:][)(|]" # emoticons color body brightcyan default "[ ][*][^*]*[*][ ]?" # more emoticon? color body brightcyan default "[ ]?[*][^*]*[*][ ]" # more emoticon? color body red default "(BAD signature)" color body cyan default "(Good signature)" color body brightblack default "^gpg: Good signature .*" color body brightyellow default "^gpg: " color body brightyellow red "^gpg: BAD signature from.*" mono body bold "^gpg: Good signature" mono body bold "^gpg: BAD signature from.*" color body red default "([a-z][a-z0-9+-]*://(((([a-z0-9_.!~*'();:&=+$,-]|%[0-9a-f][0-9a-f])*@)?((([a-z0-9]([a-z0-9-]*[a-z0-9])?)\.)*([a-z]([a-z0-9-]*[a-z0-9])?)\.?|[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)(:[0-9]+)?)|([a-z0-9_.!~*'()$,;:@&=+-]|%[0-9a-f][0-9a-f])+)(/([a-z0-9_.!~*'():@&=+$,-]|%[0-9a-f][0-9a-f])*(;([a-z0-9_.!~*'():@&=+$,-]|%[0-9a-f][0-9a-f])*)*(/([a-z0-9_.!~*'():@&=+$,-]|%[0-9a-f][0-9a-f])*(;([a-z0-9_.!~*'():@&=+$,-]|%[0-9a-f][0-9a-f])*)*)*)?(\?([a-z0-9_.!~*'();/?:@&=+$,-]|%[0-9a-f][0-9a-f])*)?(#([a-z0-9_.!~*'();/?:@&=+$,-]|%[0-9a-f][0-9a-f])*)?|(www|ftp)\.(([a-z0-9]([a-z0-9-]*[a-z0-9])?)\.)*([a-z]([a-z0-9-]*[a-z0-9])?)\.?(:[0-9]+)?(/([-a-z0-9_.!~*'():@&=+$,]|%[0-9a-f][0-9a-f])*(;([-a-z0-9_.!~*'():@&=+$,]|%[0-9a-f][0-9a-f])*)*(/([-a-z0-9_.!~*'():@&=+$,]|%[0-9a-f][0-9a-f])*(;([-a-z0-9_.!~*'():@&=+$,]|%[0-9a-f][0-9a-f])*)*)*)?(\?([-a-z0-9_.!~*'();/?:@&=+$,]|%[0-9a-f][0-9a-f])*)?(#([-a-z0-9_.!~*'();/?:@&=+$,]|%[0-9a-f][0-9a-f])*)?)[^].,:;!)? <>\"]"
Now to bring everything together. Create a file called
neomuttrc. This file would
link the files that we have created thus far.
$ cat neomuttrc source mailboxes.muttrc set realname="Ou Rname" set sort='reverse-date' set use_from=yes set ssl_starttls=yes set ssl_force_tls=yes set editor="vim" set rfc2047_parameters = yes set sleep_time = 0 # Pause 0 seconds for informational messages set markers = no # Disables the `+` displayed at line wraps set mark_old = no # Unread mail stay unread until read set mime_forward = yes # attachments are forwarded with mail set wait_key = no # mutt won't ask "press key to continue" set fast_reply # skip to compose when replying set fcc_attach # save attachments with the body set forward_format = "Fwd: %s" # format of subject when forwarding set forward_quote # include message in forwards set reverse_name # reply as whomever it was to set include # include message in replies set sidebar_visible = yes set sidebar_width = 20 set sidebar_short_path = yes set sidebar_next_new_wrap = yes set mail_check_stats set sidebar_format = '%B%?F? [%F]?%* %?N?%N/? %?S?%S?' source colors.muttrc macro index O "<shell-escape>offlineimap <enter>" "run offlineimap to sync all mail"
Phew! With that our
neomutt should be configured and ready to go. Just run
And you'd be greeted by something that looks like this
If you're a neomutt beginner like me, do bookmark the getting started guide.
Make sure your terminal's
$TERM variable is properly set. Otherwise,
the keybinds may not work. In my case
urxvt didn't register the
F3 keypresses, as I had manually set
~/.Xresources. Remove that, and you should be good.
$ echo $TERM rxvt-unicode-256color
The config files in this post are butchered and in some cases like the color definitions, are outright "borrowed" from the above mentioned links. I cannot thank them enough for their efforts.
Hope you gained something worth while from this post.
Happy Hacking & have a great day!
