no incoming mail

[darthpaul]

We had almost two weeks since my last issue. Today we stopped getting any incoming mail. Our spam filter is reporting emails coming in and is forwarding them to the email server running ispconfig, but no emails are coming through to the users.

I tested an admin email account in outlook and it says it cannot get a response from the pop3 service.

Virtusertable is good and the recycle bin has been behaving since I updated php. No errors in the log file, no lock files, conf files are good.

How do I check to ensure the incoming mail service is running? If it is down how do I ensure that it starts at boot?

Any help would be greatly appreciated.
