I host an e-mail discussion list for my GriefLossRecovery.com Web site. We have been experiencing a number of problems with soft bounces halting messages altogether. The list is fairly active, so it's a big pain to have to go into Topica to delete the offending e-mail address to get the messages going again.

Have you had a similar problem with Topica? If yes, how did you resolve it?

Thanks.
