(No, not spam. Newsletters people subscribed to.) When you get a bunch of failures, are some messages sent correctly and others die, or does everything break during a fixed window of time? Having everything run fine, then everything fails for a while, then works again with no apparent change on your end, sounds like some service you're relying on is going away then coming back. If so : * Maybe DNS is slow sometimes? * Is qmail sending mail directly, or just handing the mail off to another server (smarthost, I think its called)? If that upstream server is busy/unavailable periodically, that would be an issue. alex
