Query about list policy?

[Andy R]

Greetings for a second time today,


As a quick query, what is the policy about linking to user-scripts and 
small addons ? I've used a couple of perl scripts to help me with dspam 
training from dovecot-antispam and imapsieve triggering for sorting and 
feeding messages to dspam in the background. They are most likely not 
the greatest but seem to work at least. I've posted them to github, but 
just wanted to ask whether it was an issue if i linked them here, or if 
they would need any review before posting or any other answer?



Many thanks, and to Aki Tuomi and the dovecot team also.

Re: Replacement for antispam plugin

[Andy R]

Greetings to the list :)


I've been meaning to ask a couple of questions about the imapsieve for 
antispam.



Firstly, I guess that the example at the bottom of the page 
"https://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/IMAPSieve;  is meant 
to link to the new example at 
"https://wiki2.dovecot.org/HowTo/AntispamWithSieve; now?



Also... in "imapsieve_mailboxX_name = ${directory}"  is the string a 
literal, or is it working with the 'special use' flagged directories 
from the xx-mailboxes.conf? I'm asking as though I only have a few users 
to worry about, different mail clients each have their favourite special 
folders. IE thunderbird uses "junk" but one Outlook express version 
likes "Junk E-mail" and I have a different favourite from another 
version of OE too. So in mailboxes.conf I just added extra special use 
lines which seemed to make things happy. Otherwise I ended up with the 
server configured 'spam' folder showing as basic folder, and then each 
client adding it's own chosen spamfolder each time too.



But, if the imapsieve is only matching to literal foldernames, should I 
just duplicate the trigger lines for each type of junk folder or is 
there a method to have the sieve script enumerate all the options listed 
by 'special use'  or is there a better method for this? I want to put 
the spam-mail-filing script as a global sieve script as all users will 
need it, rather than duplicating out for each user.




Many thanks ,


Andy R

Hi!
Since antispam plugin is deprecated and we would really prefer people
not to use it, we wrote instructions on how to replace it with
IMAPSieve. Comments and suggestions are most welcome.

Re: [Dovecot] dovecot-lmtp does not work

[Andy R]

Hi there,

Have you added 'lmtp' to the protocols line in dovecot.conf ? It's not 
listed in your doveconf -n.


IE :-

# Protocols we want to be serving.
#protocols = imap pop3 sieve
protocols = imap pop3 sieve lmtp


For logging, set mail_debug = yes (in 
/etc/dovecot/conf.d/10-logging.conf on my system).

Dear Community,

I've got a weird problem regarding lmtp setup with dovecot 2.0.19 on ubuntu
12.04.2 LTS. My reference of the configuration is at
https://library.linode.com/email/postfix/postfix2.9.6-dovecot2.0.19-mysql ,
and my configuration is identical to it with the exception of opening the
110 pop3 port, and enabling plain text auth. Everything from imap, smtp,
pop3 (including auth) works except for lmtp.

I saw thousands of the following messages in /var/log/mail.log:

May 31 09:05:24 postfix/lmtp[3664]: 2FD80321F4: to=myaddr...@me.com,
relay=none, delay=0.41, delays=0.41/0/0/0, dsn=4.4.1, status=deferred
(connect to me.com[private/dovecot-lmtp]: No such file or directory)

And it happens when an incoming email is received.

Here's the output of configuration:

}

This problem has been discussed here:
http://serverfault.com/questions/512219/dovecot-lmtp-does-not-exist . I've
then tried switching from unix socket to inet listener, and still got the
same result. I cannot get lmtp service to start.

I'm also seeing no errors in the log when dovecot is restarted (see the
above link for the log).

I'm wondering how do I go about troubleshooting this problem? What might be
the possible cause? Is it possible for dovecot to output verbose logs
regarding service startups?

Thank you.
