Re: [qmailtoaster] messages stuck in the queue

There's not a whole lot you can do. What the spammers are doing is sending an email to your domain (bad address), with a different return address (usually also bad), so your machine is trying to bounce the message back to the sender, which as I said is also invalid. I set my queuelifetime to something reasonable like 2 or 3 hours, which helps clean them out of the queue faster. It's also a good idea for businesses, since if they send a message and there is an error they get a message back in 2-3 hours, instead of 5 days like the default. Gives them a chance to see their error, and send the message again after correcting. Other than that, some good BLs is about the best you can really do.
