I have a problem with incomming mail with my server, it wont receive! Anyway, i conacted the guys who colo'd my server (LayeredTech) and they fixed this issue twice in a day, it kept comming back. It has came back once again. The emails sent back to me where: ----------- Scott, I have Flushed your iptables rules and your mail server is now accepting connections. You should look into configureing iptables so if this happens in the future oyu can correct the issue quicker that what it takes to submit a ticket. Thanks, John -------------- Scott, It appears there was a problem with your 'iptables' ruleset and it was blocking the ports used by your mail server. I have installed a simple iptables firewall ruleset and it appears to be working now. Thanks Jeremy -------- Can you guys help me to STOP this issue comming back completely, I have apf+bfd installled, maybe that has its part but who knows? OR maybe just the IPTABLES. is there a way to keep them the same... Please this issue is rather annoying. Help is ver very much welcomed!
