Hi list,
I'm running postfix under Wheezy on my VPS, using a more or less
out-of-the-box configuration. My users access their mail via IMAP.
I subscribe to a number of mail lists, such as this one. I currently use
Thunderbird's filtering capability to sort mail into a number of
subdirectories within my inbox, which works fine, but requires me to set up
all my workstayions (laptop, home, work) with the same filters. I have now
acquired an Android smartphone, which has no filtering capability. In any
case, keeping a number of workstations in sync is a pain.
So, I'd like to perform the filtering on the server (for my user initially,
then perhaps for others). My extensive googling reveals that there are many
tutorials for filtering spam, but that's not really my problem.
I can't find any tutorials on how to set up filters based on, say subject:,
from:, or to: fields, but feel certain such must exist.
Can any kind person direct me to a suitable tutorial, please?
You can use:
- sieve, a language for controlling filtering on IMAP servers.
Supported by Thunderbird but not very much else.
- procmail, a language for filtering on delivery (postfix will
call it) -- widely known, but arcane syntax and requires shell
access to edit or place the ~/.procmailrc
- maildrop, aka mailfilter, a language for filtering on delivery
(postfix will call it, too) -- less widely known, but has
syntax that is much more readable than procmail. Requires
shell access to place a ~/.mailfilter file.
All of these have Debian packages.
