Re: [Dovecot] deliver + quota failure

29 Oct 2006 · *before*

      I investigated the deliver with quota's bug a little more (rc10, mysql,
virtual domains, maildir). My log files reads:
deliver(test@ruijs.cc): Info: msgid=000f01c6fac1$bd4e8670$8801a8c0@Moskou:

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:

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

  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.
