What did you do?
Two issues I run into: - setting up clients to talk to servers on port 25. It can work, but you are supposed to use port 587. Some network block 25, also, if you only allow authenticated connections on 587, then you can be less stringent on ip restrictions, SPF etc... - sometimes when going via cell data network, I wouldn't get a hostname at all, and I was refusing connections when a forward lookup for the host didn't match the ip. I relaxed a bunch of rules on 587, and that solved that. -- http://yves.zioup.com gpg: 4096R/32B0F416 _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
