No emails show in email programs

[vrep]

Hello all,

I've come across a very weird problem. When I log into my email program (Mail on Macos) or webmail (Horde) I don't see any emails in my Inbox. However, in my user dir Mail/cur there are many emails still.

Any ideas how to fix this?

Then another thing: after a reboot some days ago, my email doesn't get delivered anymore. My server is reachable from outside:

[ubuntu@ip-172-31-22-15:~]$telnet dhoek12.myownb2.com 25
Trying 77.172.120.205...

Connection closed by foreign host.

Can you telnet to port 143 as well? My guess is that the imap server isn't running.
