Cant receive mail from hotmail and facebook

Weird behavior on my server, i can receive mail from gmail but not from hotmail and facebook, when i send a mail to hotmail it receives normally but when i reply i get an error message back:

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

Any ideas on what could be wrong? is it even my server?


You may want to take a look in your email logs, either in /var/log/maillog or /var/log/mail.log, to see if there’s any errors or other clues as to what’s going on.


I had set the server to ALWAYS use TLS but it seems that not every server out there supports secure connection, i was having a hard time keeping my ip out of PBL and Black Lists because i was sending mail without tls/ssl.

If you set “If requested by client” and configure every single smtp client (including roundcube) to use TLS you will only send secure email but you can still receive from servers that won’t send you secure email.

Well thanks a lot eric hope this helps someone else too…
