Is anyone else having this trouble? For the past week, a lot more spam than usual seems to be getting through to our users. For example, some users who were receiving four or five spam emails a day are suddenly seeing fifty to a hundred a day.
Looking at the SMTP log in Mail Manager, I can see lots of emails being blocked with Rejected: RBL and Rejected: RDNS/HELO, and even some with Rejected: Spam (but not as many as normal, I suspect).
I'm trying to work out whether someone has recently discovered a new way of getting round the spam filter, or whether there's a problem with my Astaro box. So, is anyone else seeing this problem?
