Hi everyone, I hope someone can help me with a question. I apologise if it's been asked before - I couldn't find anything while searching the forum.
We discovered our server on 212.227.77.248 was SpamCop's blacklist last Wednesday. Unfortunately it turned out we did have the server configured to act as an open relay, and it was being used to send spam.
We belived we had resolved the issue and by Friday we were no longer blacklisted.
Came into work today (Monday) and checked the IP on SpamCop, and we are blacklisted again.
The initial ban was from user reports. The current one is user reports and 1 spamtrap.
My question is, is it possible that the latest ban is still from the spam we were relaying previously, that have just taken a few days to be reported, or is it likely that we have a further problem?
Thanks for reading.
Michael
