I think they said it was a recipient limit. > If the limit is on transactions, you can leave Mailman's > default settings for SMTP_MAX_RCPTS (500) VERP (No) and > personalization (No) and Mailman will group domains into a > few transactions with many RCPTs and this may help. I don't think we'd have access to those settings with cpanel anyway, would we? > But the question remains.

They claim we were sending spam, and they noticed a huge spike in the amount of SMTP traffic (2.5GB vs the usual 10MB or so) on the 10th. they didn't show us stats for the numbers of emails, only the size. We think someone somehow hacked our account and really was sending spam, although we've only got their word for it. If they were sending it to list members that would explain the mail rejections I was seeing in my own logs. Anyway, it's obvious that the topic of these limits is an old one, and the only new thing here is that we somehow got lucky and they didn't apply them for a long time. I think I'd have prefered if we'd known from the start. Time to concentrate on moving to a new provider.
