A few feature implementation requests for a future release of iRedMail.

-Ability to auto delete messages.

Adding this to crontab:
# Cleanup Drafts, Sent, Junk, Trash
0 3 * * * /usr/local/bin/dovecot-expunge.sh

and creating this script /usr/local/bin/dovecot-expunge.sh with the following contents:

#!/bin/bash
#
DOVEADM="/usr/bin/doveadm";

$DOVEADM expunge -A mailbox Drafts savedbefore 365d
$DOVEADM expunge -A mailbox Sent savedbefore 365d
$DOVEADM expunge -A mailbox Junk savedbefore 30d
$DOVEADM expunge -A mailbox Trash savedbefore 30d

will remove messages in Draft and Sent folders older than 365 days, and remove messages older then 30 days in the Junk and Trash folders.

-Remove Postfix headers on outgoing messages by default. Postfix gives away lots of information that most probably wouldn't include given a choice, especially when sending with a client such as Thunderbird or any iPhone or Android SMTP mail app. With the below solution the log files still have this information for outgoing messages if needed.

Adding a file called: /etc/postfix/smtp_header_checks

with the below:

/^\s*(Received: from)[^\n]*(.*)/ REPLACE $1 [127.0.0.1] (localhost [127.0.0.1])$
/^\s*User-Agent/        IGNORE
/^\s*X-Enigmail/        IGNORE
/^\s*X-Mailer/          IGNORE
/^\s*X-Originating-IP/  IGNORE

and editing /etc/postfix/master.cf by finding:
submission inet n       -       n       -       -       smtpd
 
and adding:
   -o cleanup_service_name=subcleanup

and by adding
subcleanup unix n       -       -       -       0       cleanup
    -o header_checks=pcre:/etc/postfix/smtp_header_checks

to /etc/postfix/master.cf
