Which mail transport uses XMail?

[Nils Doormann-2]

Hello list,

I am using xmail 1.25-4 in conjunction with dovecot-imapd 1:1.2.4-2 and spamassassin 3.2.5-6.

The install packages come from Debian squeeze/sid and everything works fine so far.

However, I wonder how xmail delivers mail to final Maildirs and how a different Maildir based on, say as-spam-tagged content, can be selected.

My intention is to set up sieve for dovecot-imap, but this requires to modify the local mail delivery agent. This is possible for exim, postfix and others through their configuration files as mentioned in http://wiki.dovecot.org/LDA. How can this be achieved in XMail?

Does xmail use procmail for that?

As an alternative: Is it possible to achieve though another filters.in.tab entry?


Thanks in advance,

Nils

Can you explain better what this alternative delivery method will have to do?

That would work.

Hi Davide, thanks for your quick reply.

I use sa_filter.pl filter script in filters.in.tab from http://www.drakeconsult.com/xmail/ to invoke spamassassin, which modifies the mail in the way that it adds an "X-Spam-Flag: YES" header entry in case of the message detected as spam.

My intention now is to directly deliver the tagged mails directly to a Maildir "subfolder" like

...spool/xmail/domains/domain.tld/%u/Maildir/Spam

instead of

...spool/xmail/domains/domain.tld/%u/Maildir

1. While in postfix for example this can be easily modified through an entry its master.cf configuration file I dont know where to configure xmail accordingly.

2. Using dovecot-imapd with sieve mailfilter can handle direct mail delivery to other maildir directories than the default of .../domains/domain.tld/%u/Maildir, as describerd in http://wiki.dovecot.org/LDA/Sieve#SpamAssassin_tagged_mail_filtering . As far as I understood this is accomplished by "deliver", a local delivery agent that comes with dovecot and runs in place of the lda provided by the mta, say postfix's sendmail/procmail or whatever.

3. For this to set up the program/method for local delivery has to be replaced by "deliver" which in turn handles mail filtering through sieve.

Maybe this can be easyer achieved through a filter.in.tab entry and I'm thinking too "dovecot"... If so, I havent found a way to do yet.

I hope, I've expressed myself more precisely now :)

Regards,
Nils

Actually, you may be better off using a "filter" command inside the users
mailproc.tab for that.

Hi Davide,

only for feedback.

I solved this for me very easily in modifying the above mentioned sa_filter.pl to let it return a value of 6 (reject mail with sender notification) when detecting spam through spamc. It turned out that spamassassin is doing a very good job at that point which the mail users can rely on. So, for now there's no need to futher collect spam anymore...

I meanwhile played a little with a mailproc.tab filter but this could be another issue one day. ;-)

Thanks for your help.

Regards, Nils
