I discover an other problem when the pop3proxy is enabled my server is unable to fetch email with mapilab and I made a test and revert back to astaro 8.305 and everything is wokring fine ???
I don't know how to make the POP3 Proxy work to allow an internal server to receive proxied email, but I'm not familiar with mapilab. The POP3 Proxy allows an internal client to have email on an external mail server checked with anti-spam and anti-virus. If you have an internal mail server, you should use the SMTP proxy to check inbound email.
Did that help?

Yeah that would be the best practice but email account can only be fetch by POP3, MapiLab work as a POP3 client on exchange serveur and redirect all email fetched by POP3 to the right exchange email account ...
If MapiLab can access each POP3 account separately and it has the credentials for each user, then you may be able to make it work with the POP3 Proxy.
Another possible solution depends on where/how MapiLab is hosted and how it communicates with Exchange. If it gathers email via POP3 and then sends it via SMTP to Exchange, I would recommend a different approach. Have MapiLab relay email to the Astaro SMTP Proxy instead of Exchange, and have the Astaro then send it via SMTP to your Exchange server.
Would that work?
