[Dovecot] Executing SQL update upon login
Hi,
I'm using SQL authentication in dovecot, and was wondering if anyone had any ideas as to how I could run an UPDATE statement upon each login, to set time of last login (and other interesting stuff) in the database table.

Set mail_executable to point to a script:
#!/bin/sh
echo "update blah where user = '$USER'" | mysql ..
exec /usr/local/libexec/dovecot/imap

Won't the overhead on that be pretty high? Considerings it now has to wrap the imap command in to a script.

I doubt overhead would be much of a problem, since all the shells will use shared memory. The problem I see is that at the time you're running the update, you have not yet authenticated the user, so your data could be unreliable.

No, mail_executable is run only after a successful authentication.

Would it not be better to add a on_login_query which allowed access to a list of variables, IP address, username, password etc.
on_login_query = UPDATE users SET last_login = NOW(), last_ip = %i WHERE user = %u

Maybe, since so many people have already asked for this. Patches welcome ;)

Code to do this kind of thing is available in tpop3d (another great
POP3 server), only that I don't know no C, and hence how to "borrow" it
from there ;)
