Turning on the Mail Service (imap) does not open ports 143 nor 993
Hello folks,
I have a new install of Mavericks Server. I have an issue with the mail service, namely, even when turning it on, the ports 143 (imap) and 993 (imaps) appear to stay closed. The mail service seems to run fine (at least, that is what Server tells me). But a simple port scan shows that neither ports 143 nor 993 are open. Which makes it difficult for clients to connect to the server.
Anyone is experiencing this? Does anyone have an idea on how to open those ports? I have no experience with the pfctl command, which is probably the way to go?
Thank you very much for your help. Regards.
