[Dovecot] Pop-before-smtp and MySQL?
Hi, I found that dovecot have many nice features. Now I write because I'm tring to setup the dovecot server, I would substitute a qpopper daemon (patched for mysql authentication) The problem I find is to set up the pop-before-smtp using sql (mysq) as written in http://wiki.dovecot.org/moin.cgi/PopBSMTPAndDovecot (Waiting for post_login ;-) I would use the script popbsmtp.sh and not a perl pig. (I'm using qpopper patched to store the relay IP in mysql and it works) I set .my.cnf in /root What happen is that the $3 don't contain the IP that should be written to the DB. Is there something I miss ? I tried to modify the dovecot.conf file like this mail_executable = /usr/local/libexec/dovecot/popbsmtp.sh /usr/local/libexec/dovecot/pop3 %r "%r" and it write to the db the litteral value %r and not the ip, otherwise it write nothing. the connection with mysql works and any other operation on it works. this should be the last step for my setting.
Have you any hint?
Thanks in advance and best regards

I can't help with your pop-before-SMTP, but I can suggest that you not do that. :) The better way to do it is with SMTP AUTH, which most MUA's should support these days.
If your MTA is Postfix (which appears so from your headers) Timo has a patch which ties in SASL AUTH support without using Cyrus SASL. I use it and recommend it highly. See the Postfix SASL_README and the patch at http://dovecot.org/patches/postfix/ (for Postfix 2.2.x) or my own ports of it to the 2.3 snapshots: http://www.nodns4.us/postfix-2.3-20051121-dovecot-auth.patch.gz
http://www.nodns4.us/postfix-2.3-20050630-dovecot-auth.patch.gz still exists for those who got on the bleeding edge but were too lazy to stay there. :)

I'm not the original poster of the question, yet I have a question about this patch.
What would be the benefits of using this patch? I mean, dovecot is supposed to have its own SASL implementation (as stated in the docs) and we are even using it. So why would one need a specific patch for postfix when dovecot is completely on its own feet?

The main benefit is that you don't have to use nor install Cyrus SASL. It's also very simple to set up: once you set all the options it Just Works.

IIUC Postfix cannot use Dovecot SASL without the patch. Timo could probably give a definitive answer.

Ah, I see, so it's the other way round, postfix uses dovecot for SMTP AUTH then? That would be _very_ cool indeed.

The first thing to do is some debugging: in the popbsmtp.sh script write the received parameters to a file, and decide where the problem is! For exemple,
echo "Login from $3, parameters 1=$1, 2=$2, 3=$3, 4=$4" >> /var/log/dovecot3I did not need to put %r in the dovecot.conf, my line is
mail_executable = /usr/lib/dovecot/popbsmtp.sh /usr/lib/dovecot/pop3If you put any junk afterwards, you will find that it's not $3 anymore but $4 or $5 or whatever.
My dovecot version is a 1.0stable.
I am using pop-before-smtp with no problems with dovecot.
String is:
$pat = '^(... .. ..:..:..) \S+ dovecot: imap-login: Login: user=<\S+>, method=\S+, rip=(\d+\.\d+\.\d+\.\d+)';

Thanks again, I made some debugging but it didn't helped. I wrote something similar to the line you suggested at the top of the popbsmtp.sh script this is the result:
dovecot: Nov 28 14:50:41 Info: Dovecot v1.0-stable starting up dovecot: Nov 28 14:50:42 Info: auth(default): mysql: Connected to postfix Login from , parameters 1=/usr/local/libexec/dovecot/pop3, 2=, 3=, 4= dovecot: Nov 28 14:50:59 Info: pop3-login: Login: teo@xarrampicate.it [192.168.100.70]
it seems that no variable is passed during the execution of the mail_execute commands
compilation options: ./configure --with-mysql --without-passwd --without-passwd-file --without-shadow
the dovecot.conf file is:
protocols = pop3 ssl_disable = yes disable_plaintext_auth = no log_path = /var/log/dovecot3 log_timestamp = "%b %d %H:%M:%S " login_user = dovecotauth first_valid_uid = 50 default_mail_env = mbox:/tmp:INBOX=/var/spool/mail/%u mail_log_prefix = "%Us(%u):" protocol imap { } protocol pop3 { mail_executable = /usr/local/libexec/dovecot/popbsmtp.sh /usr/local/libexec/dovecot/pop3 } auth default { mechanisms = plain passdb = sql /usr/local/etc/dovecot-sql.conf userdb = sql /usr/local/etc/dovecot-sql.conf user = dovecot }
the popbsmtp.sh is:
#!/bin/sh
echo "Login from $3, parameters 1=$1, 2=$2, 3=$3, 4=$4" >> /var/log/dovecot3
(
IP=echo $3 | sed 's/\]//'

then
export HOME=/root/
echo "replace into relay_ip VALUES('$IP','RELAY',now());" | mysql
postfix
export HOME=/
fi
) >> /var/log/dovecot3 2>&1
exec $*
dovecot is: 1.0-stable
still in the limbo... thanks for any help te0x

It does seems that way. Sorry, I cannot explain that. Maybe you have a different version than I do, but they are both -stable and your dovecot.conf syntax resembles mine. No idea... maybe something in the compilation (you give your compilation options so I suppose you compiled it yourself; I took a debian package).
I can add, i run dovecot standalone not inetd or xinetd. does it change something about the pop-before-smtp issue ?
Thanks te0x

Mine is standalone, so that's not the problem.
Sorry. Since nobody else is helping, try another way...

I don't know why that script had $3 there, Dovecot has never given any parameters to imap/pop3 processes. But the IP address exists in IP environment, so you can just remove the "IP=.." line from the script and it should work. I updated the wiki already.

Never? Then I have some bizarre version compiled with an obscure patch by someone else... my config is
% protocol pop3 { % pop3_uidl_format = %f % mail_executable = /usr/lib/dovecot/popbsmtp.log /usr/lib/dovecot/pop3 % } % % protocol imap { % mail_executable = /usr/lib/dovecot/popbsmtp.log /usr/lib/dovecot/imap % }
% # head -3 /usr/lib/dovecot/popbsmtp.log % #!/bin/sh % % echo "Login parameters 1=$1, 2=$2, 3=$3, 4=$4, IP=$IP" >> /var/log/dovecot-t
I added on IP just now, never thought it could be there already.
% # tail -1 /var/log/dovecot-t % Login parameters 1=/usr/lib/dovecot/imap, 2=[xxmyloginxx, 3=xxxmyIPxx], 4=, IP=xxxmyIPxx
So, yes, IP is already in the environment, cool, the IP= line in my script was more or less useless (I add a pipe grep to avoid inserting local-net IPs, but that's minor), but on the version I have (1.0-stable, debian testing package 0.99.20050712-2), $2 and $3 do get there in *some* way . . .
Good to see the problem solved in any case, and since removing IP= would work on my version too, wiki is OK without further modifications.

Oh. This is done with verbose_proctitle=yes setting, but it's only meant to be human-readable, and you shouldn't rely on it being in any specific format..
Thanks very much, It works ! Now I can manage the swich from qpopper to dovecot and offer also the imap service. I hope it helps somebody else. Bye Te0x

wiki is OK without further modifications.
The problem was that the solution I posted on the wiki only worked for me because an unrelated diagnostics switch was set, and this was not specified. Timo corrected my code so it works in the general case, and thus the original problem (the code on the wiki not working) will not happen again.
The wiki URL is http://wiki.dovecot.org/moin.cgi/PopBSMTPAndDovecot
