MailEnable port 25 issue
I have clients who are using Mail Enable Standard and Enterprise version are encountering some issues in sending emails. Logs showing the "connection refused" error. For every client, I try to telnet the machines from public as well as private network on port 25 but unable to connect. The issue resolved after I restart the machines. Kindly tell me why I am encountering the mentioned issue. As, it is not a best approach to restart the machines everytime the issue occurs.

Re: MailEnable port 25 issue
Hi,
When you say your restarting machines do you mean your restarting the MailEnable servers? A connection refused is most likely caused by the "Abuse detection and prevention" policy. The connection from the client is being refused most likely because it has been detected as abusive by either; invalid authentication attempts or bad commands. Therefore you need to inspect the relevant service log files that the client connects to. I.e IMAP, SMTP POP etc. You can also disable the abuse detection policy to see if this is in fact the cause of the problem. To disable the policy please see:

Re: MailEnable port 25 issue
By restarting the machine means Restarting the server not MailEnable and the option you were talking about "Abuse detection and prevention" has already been disabled.
