Re: imapd 2.5.7-8 with virtual domains and sendmail config

Stefan,

Thanks for your suggestion.

The virtusertable is actually being used in my config. I think my problem is in the cyrusv2 definition.

My virtusertable contains a mapping domain@xxxxxxxxxxx   joe@xxxxxxxxxxx

The domain part of the address is getting stripped off, and the servers host.domain.tld added, before talking to imapd over lmtp socket.

# sendmail -bv domain@xxxxxxxxxxx
domain@xxxxxxxxxxx... deliverable: mailer cyrusv2, user joe@xxxxxxxxxxxxxxxxxxxxxxxx

Suggestions welcome :)

Regards
Mogens

    Hi Mogens,

    I have almost the same config as you do. Except for not using
    virtusertable. So I just ran a little test and got exactly the same
    result that you did: it looks like virtusertable is never checked
    and delivery fails. 

    I don't have a solution for you (yet), maybe someone on this list
    does, but I do have a workaround if you need it. I also use userdb.
    Adding the same entry you use in userdb solves the problem for me.
    Delivery goes smoothly. 

    HTH

          This is driving me nuts. I really need some help here.

          I'm running a test sendmail (8.15.2) and a cyrus-imapd
            2.5.7 on

            slackware 14.1 running in a virtualbox.

          joe@xxxxxxxxxxx
            is a valid user on cyrus, not a login (linux) user.

          From cyradm:

            localhost.localdomain> lm

            user/joe/Drafts@xxxxxxxxxxx
            (\HasNoChildren)                             

            user/joe/Sent@xxxxxxxxxxx
            (\HasNoChildren)                               

            user/joe/Trash@xxxxxxxxxxx
            (\HasNoChildren)                              

            user/joe@xxxxxxxxxxx
            (\HasChildren)                                      

          I have an entry in virtusertable for domain@xxxxxxxxxxx
            mapping to

            joe@xxxxxxxxxxx

            example.com
            is in local-host-names file.

          I have shaved my cyrusv2.mc down to a bare
          minimum, and the relevant

        section in sendmail.cf
        show the difference between cyrusv2.m4 and

        my cyrusv2.mc
          (R=EnvToL/HdrToL => R=EnvToSMTP)

          -------

          Mcyrusv2,    P=[IPC], F=lsDFMnqXzA@/:|m,

                  S=EnvFromSMTP/HdrFromL, R=EnvToL/HdrToL, E=\r\n,

          This is what my current cyrusv2.mc look like:

                  A=FILE /var/imap/socket/lmtp

        When checking address test:

          echo '/map virtuser domain@xxxxxxxxxxx' |
          sendmail -bt

          ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)

          Enter <ruleset> <address>

           (0)p_lookup: virtuser (domain@xxxxxxxxxxx)
          returns joe@xxxxxxxxxxx

        It looks promising, but then a ruleset 3,0 test

          echo "3,0 domain@xxxxxxxxxxx" |
          sendmail -bt

          ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)

          Enter <ruleset> <address>

        When sending a mail to domain@xxxxxxxxxxx I
          get in the logfile:

          failed: Mailbox does not exist

        I'm totally lost, and have no idea where to look.
