mail piler not accepting telent connection and mails

[Santosh Sharma]

For newly configured mailpiler, it’s not accepting any connection on port 25 from outside of server. I stopped postfix at it was using same port as piler. I tried running piler on other ports with local IP instead of 0.0.0.0 but telnet to any port for piler is not working. I had already checked firewall and other network settings. It’s also not able to receive any of email and nothing much coming in maillog. Kindly share your thoughts on this and help in fixing it.

Piler works just fine. Port 25 access is blocked at the network level with either network acl or security group settings.
