<code>
 apt-get install alpine
</code>

==== Pine User Config ====
<code>
vi /home/user/.pinerc
user-domain=domainame.com
inbox-path={server.domain.com/user=username/ssl/novalidate-cert}INBOX
customized-hdrs=From: Firstname Surname <user@domain.com>
folder-collections={server.domain.com/user=username/ssl/novalidate-cert}INBOX.[]
</code>
With the above, you should be able to login to imaps and send emails.

=====Add-In for Pine for Gnupg -- Pinepgp=====

===== Manual gpg and Pine =====
<code>
 vi /$HOME/.pinerc
 ##include/replace with the lines below.
 display-filters=_LEADING("-----BEGIN PGP MESSAGE-----")_ /usr/bin/gpg --decrypt,
                _LEADING("-----BEGIN PGP SIGNED MESSAGE-----")_ /usr/bin/gpg --decrypt
 sending-filters=/usr/bin/gpg --clearsign

When sending an email it will ask you for a "filter". Hit CTRL + N to select gpg sign. Additonal sending-filters can be added for encrypt etc. as on: http://computing.ee.ethz.ch/.doc/pgp/index.html#howtosetuppineforuseiwthgpg
</code>

==== GPG Password Cache ====

In Debian bullseye when reading a gpg email, it will prompt for password and then spawn: /usr/bin/gpg-agent --supervised
Note this caches your GPG password. To prevent gpg password caching:
<code>
vi /home/user/.gnupg/gpg-agent.conf
#add the following
default-cache-ttl 0
</code>
Test. You can also kill the gpg-agent process, but setting cache to 0 is easier.

===== Automatic Login for Pine =====
Pine can automatically login to a imap server on *nix. Pine can use ssh keys to login to the mail server and initiate a imapd command in order to access email(imap) folders.

Because Pine uses ssh keys - it does not work over ssl (2 different security methods) - and therefore pine must access port 143 on the mailserver (as opposed to 993 for imaps).
<code>
  - Setup ssh keys - so you can login to the mailserver (*nix) directly. See the tutorial on this website for [[Sshkeys]]
  - Test the above with "ssh mail.server.com /usr/bin/imapd" and it should login for you with PREAUTH.
  - Configure pine, either in the global file in /etc/pine.conf or per user in $HOME/.pinerc with the following lines:
 smtp-server=mail.server.com/novalidate-cert 
 inbox-path={mail.server.com/novalidate-cert}INBOX 
 folder-collections={mail.server.com/novalidate-cert}INBOX.[[]]
 ssh-path=/usr/bin/ssh
 ssh-command="%s %s -l %s exec /etc/r%sd"    <nowiki>//</nowiki> %s = imap, so its running the command /etc/rimapd on the mailserver.
What is happenning - is that pine is ssh'ing into the mailserver and running this command [[ssh-command="%s|%s -l %s exec /etc/r%sd"]] to run imapd for the user.

</code>
This works fine for mbox. If Maildir is on the mailserver - a special script must be put in place before running imapd by the user.

Instead of:
<code>
 ln -s /usr/bin/imapd /etc/rimapd
Do the following:
 vi /etc/rimapd  #make sure its not in place already!
  
 #!/bin/sh
 exec /usr/bin/imapd $HOME/Maildir 2>/dev/null
 
 chmod 755 /etc/rimapd  #to make it executable!
</code>
That should work fine. The reason for /dev/null is so that *any* stdout or stderr is not sent to the commandline, but rather sent to /dev/null.

Also note that Pine is now accessing our server over 143 (via ssh) and as such the port needs to be open! More Info on Maildir + pine + autologin at: <br />

===== Spell Checker for Pine =====
CTRL+T calls the spell checker when composing an email in pine. The necessary bash spell packages must be installed firstly however.
<code>
 apt-get install spell aspell aspell-en aspell-bin
</code>
That should provide all the necessary packages for pine to do spell checking. I dont think it spell checks the "Subject :" entry however.

===== Pine with SSL =====
The following is a mailaccount which has ssl support. To test this:
<code>
 telnet mailserver.com 993
</code>

Because this second mailaccount has a lot of folders and its own inbox I wanted to keep it seperate from my main .pinerc. So I made a .pinerc_email2:
<code>
 vi /home/$user/.pinerc_email2
 inbox-path={mailserver.com/user=sburke/ssl/novalidate-cert}
 folder-collections={mailserver.com/user=sburke/ssl/novalidate-cert}[[]]
 #its nice how the user can be specified :)
 
 pine -p .pinerc_email2
 #open pine with a custom .pinerc
</code>

I then use screen to switch around between mail accounts. Its quicker than going in and out of mailfolders as if I had put all the mailservers in one .pinerc.
