Re: user@domain splitting not working

Also just to note that Postfix is not the problem here, that has now been ruled out

Ive been trying the LMTP protocol directly and still confirm the problem.. 220 localhost I am ready. LHLO wenn.com 250-localhost 250-8BITMIME 250-ENHANCEDSTATUSCODES 250 PIPELINING mail from:it@wenn.com 250 2.1.0 OK rcpt to:it@wenn.com 550 5.1.1 it@wenn.com User doesn't exist: it@wenn.com quit 221 2.0.0 OK

All I get in the LMTP log is.. Jul 17 22:13:57 lmtp(23016): Info: Connect from 127.0.0.1 Jul 17 22:14:16 lmtp(23016): Info: Disconnect from 127.0.0.1: Successful quit

The Auth log.. Jul 17 22:19:47 auth: Debug: master in: USER 1 it@wenn.com
service=lmtp lip=127.0.0.1 lport=24 rip=127.0.0.1 rport=41872 Jul 17 22:19:47 auth: Debug: userdb out: NOTFOUND 1

We have been using LDA in the past with our old Sendmail system, on our new mail server we were proposing to use LMTP with Postfix. LMTP does not work at all, it just keeps saying that the user is not recognised, LDA on the otherhand does work. I am unable to login via IMAP/POP using the full email address of the user even after the settings below are set. I have set auth_username_format=%n, also put username_format=%n in the userdb, even tried it in PAM but that just breaks it all. I just cant seem to make it all work, if i just use the username then its all fine but that does not resolve where i am planning to do.

Shows that auth is not honouring the %n i have. Does the username_format need to be only in the userdb section or also the passdb part?

That was done for testing to see if it made any difference when I moved to LDA, in LDA mode it seems to not care if that is %n or %u, it always takes the first part of the email address which is weird. Ive just tested again to confirm on %n and its not working so ive reverted again back to LDA which does. Seems to not matter how that variable is set it does not do anything.

When using %n ive tried to see if I can login via IMAP with the whole username but again no, this is the error, note the difference between the 'user' field on each line.

Hi Ricardo,

I seem to miss something: You are talking about LMTP and LDA, then present a log of an IMAP login attempt. Neither LDA not LMTP should need any authentification, where should the password come from? And yes, for auth you will need %n in passdb, too. username_format is not documented for passdb { driver = pam}, but you could try.

Could you post a log of a LMTP delivery, when %n is in effect _and_ you are sure have reloaded Dovecot?

In opposite to your sentence I see a %u there.
