[Dovecot] deliver + quota failure

[Mark Ruijs]

I investigated the deliver with quota's bug a little more (rc10, mysql,
virtual domains, maildir). My log files reads:

 

deliver(test at ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0 at Moskou>:
save failed to INBOX

deliver(test at ruijs.cc): Info: sieve runtime error: Keep: Generic Error

deliver(test at ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0 at Moskou>:
save failed to INBOX

deliver(test at ruijs.cc): Error:
open(ruijs.cc/test//.temp.in2sports2.vianetworks.nl.13210.72d247ac698d0019)
failed: No such file or directory

deliver(mark at ruijs.cc): Info:
msgid=<dovecot-1162066721-407295-0 at in2sports2.vianetworks.nl>: saved mail to
Junk

 

Dovecot tries to deliver, but notices quota exceeded. I don't think Sieve is
playing a role here - I added Sieve before I encountered the problem.

 

Two problems:

1)       The .dovecot.lda-dupes can't be written (that's what the
open...failed notice is about).

2)       The Quota Exceed mail seem to contain mal-formed headers (that's
why it the notice-mail ends in my junk-folder).

 

Digging into deliver.c, I noticed that auth_client_put_user_env() changes
the HOME environment from /var/mail (which is ok), to ruijs.cc/test/ (which
is the maildir, relative to /var/mail). And then fopen fails (see the trace
below). So I think that the code

 

    auth_socket = getenv("AUTH_SOCKET_PATH");

    if (auth_socket == NULL)

      auth_socket = DEFAULT_AUTH_SOCKET_PATH;

 

    ret = auth_client_put_user_env(ioloop, auth_socket,

                 destination, process_euid);

    if (ret != 0)

      return ret;

 

    home = getenv("HOME");

    if (home != NULL) {

      /* If possible chdir to home directory so core file

         could be written. If it fails, don't worry. */

      (void)chdir(home);

 

is the key. Should the chdir be done *before* the call to
auth_client_put_user_env()? I'm not familiar with the internal workings of
the Dovecot LDA, so I won't suggest a proper fix. Who will.

 

As for the mal-formed headers, I'll take a look at it later.
