Integrating Maildrop with Postfix/ClamAV/Spamassasin/Maildir

Hello list,

I have a working mail setup with Postfix and av/spam filtering through
amavis-new. I'd like to be able to filter mail into various folders
for mailing lists, spam, and other various things. I installed
Maildrop on my system and i configured Postfix to call it via the
"mailbox_command = /usr/local/bin/maildrop -d ${USER}" option. I have
googled around extensively, and I can't seem to figure out how to get
maildrop to deliver to a Maildir. I am using system users, so
everything is located in /usr/home/$USER/Maildir/. I can't seem to
find any example maildroprc file in my installation, or any examples
online. What is the best way to do this and create folders if they
don't exist? Eg, a "Spam" folder to move mail detected by spamassassin
into.

Also, as I mentioned, I currently use amavis-new for clamav and
spamassassin filtering. Would it be better to use maildrop for such
filtering? Would this give me any advantages over amavis-new?

This is my first major email system configuration, and my first time
using any type of MDA.

Thank you for your help.

maildrop doesn't read /etc/maildroprc

Hi,

I think I'm missing something obvious. I want to use for first time 
/etc/maildroprc. It seems that the file is not used at all.

I have created the file an put a single line in it:

# cat /etc/maildroprc
cc "fgozalo <at> csi.uned.es"

# ls -al /etc/maildroprc
-rw------- 1 cartero cartero 25 feb 24 08:10 /etc/maildroprc

No message delivered to "fgozalo <at> csi.uned.es". The message is delivered 
to the original recipient as if no was /etc/maildroprc. Nothing in the 
logs apart of the normal lines for delivery message in the original 
recipient.

More info:
. maildrop version:  2.5.1

Called from postfix:
. main.cf:
mailbox_transport = maildrop

. master.cf
maildrop  unix  -       n       n       -       -       pipe
   flags=ODRhu user=cartero argv=/usr/bin/maildrop -d ${user} -f ${sender}

¿Any hint?

Don't see what you mean,... I want to be able to mark mail as seen or
unseen, depending on how I filter them... filtering is the task of the
MDA (in this case maildrop)...
It sets (or should do so) some flags in the maildir filename... which
the imap server then sees and interprets accordingly.
In principle it's not only "S"een that could be interesting but all of:
   Flag "P" (passed): the user has resent/forwarded/bounced this
message to someone else.
   Flag "R" (replied): the user has replied to this message.
   Flag "S" (seen): the user has viewed this message, though perhaps
he didn't read all the way through it.
   Flag "T" (trashed): the user has moved this message to the trash;
the trash will be emptied by a later user action.
   Flag "D" (draft): the user considers this message a draft; toggled
at user discretion.
   Flag "F" (flagged): user-defined flag; toggled at user discretion.
(not sure whether T makes really sense though)

Maybe you have a maildrop filter, that generates some automatic
replies,... and you'd like to mark this accordingly.

Cheers,
Philippe.

merge dovecot-auth backend

Hi.

Perhaps you already know,... there's a patch
(http://wiki2.dovecot.org/maildrop) available to make user lookups
against dovecots own auth extension.

It seems to apply nicely and happily co-exist with the original system.
The license is also the same and there's even a nice README included.

Given that dovecot is major imap/pop3 server these days and people
like to use its own user auth system... and given that it would make
life a lot easier if this patch was merged upstream,... would it be
possible to do so?
Or at least tell, where it would have to be improved in order to get merged?

Perhaps it would be enough to merge it to the standalone maildrop :)

Thanks in advance,
Philippe.

deliver mail marked as read

Hi.

This seems to be a very common problem, at least according to Google ....

What's the right way to deliver mail (i.e. "to") but have it marked as read?
Is it cleanly possible with maildrop?

I've seen somy rather ugly hacks using "cc" and some find shell
commands doing the renaming,... but this seems to be not safe, is it?

Thanks,
Philippe.

Courier build 20111116

This is a development build of courier, courier-imap, sqwebmail, and  
maildrop packages.

Download: http://www.courier-mta.org/download.php

Changes:

• Fixed several instances of various processes failing if MIME attachment  
names could not be converted to the system locale's character set. They'll  
just get ignored.

• Optional logging of deleted messages. Document the IMAPDEBUGFILE setting,  
but open the imap log file only if it already exists, so that IMAPDEBUGFILE  
can be enabled globally, but selectively activated for individual accounts  
by creating a dummy zero-length file.

No, you shouldn't. Once again: you put a .mailfilter in each user's home  
directory, and that's where you provide mail delivery instructions for the  
recipient.

When your mail server runs maildrop, it should do that after dropping root  
and running maildrop under the recipient's uid and gid. maildrop checks  
which uid and gid it runs as, and sets $HOME accordingly.

This is all explained in the maildropfilter man page.
