This is a side-effect of the default backwards-compatible setting:
fast_flush_domains = $relay_domains
When mail is deferred, the queue manager informs the flush service if
the domain matches this list. As a result the queue manager opens any
associated tables. If you don't support ETRN, you will be much happier
after you set "fast_flush_domains" empty.
There is a comment in in src/global/defer.c:defer_append():
/*
* Notify the fast flush service. XXX Should not this belong in the
* bounce/defer daemon? Well, doing it here is more robust.
*/
if ((rcpt_domain = strrchr(rcpt->address, '@')) != 0
&& *++rcpt_domain != 0)
switch (flush_add(rcpt_domain, id)) {
case FLUSH_STAT_OK:
case FLUSH_STAT_DENY:
break;
default:
msg_warn("%s: %s service failure", id, var_flush_service);
break;
}
Perhaps if the code did get moved into the bounce service, we could
eliminate this *last* table dependency from the queue manager. I've not
looked into what the implications of such a change would be, Wietse is
away this week, but hopefully he'll still read this and respond when
he returns.
