Authenticated relay in MTA mode

AntonioPallua

Hi, I've configured XG SFOS v16 in MTA mode (mail server in DMZ).

It works except for authenticated relay:

I need to permit authenticated relay for users outside my office (imap/smtp form mobile device), pop3/imap works, smtp doesn't.

The mail client gives me the error 451 invalid HELO/EHLO or missing  RDNS when I try to send an email.

If i disable "Reject invalid HELO or missing RDNS" in the XG, then the error is: Authentication methods are not supported by the server (more or less, the error is in italian).

Can Anyone give me an hint?

 

Thank you

--Antonio

    Whilst not strictly related, I have uncovered with the help of the tech support bods an issue with MTA.

     

    Basically, you cant send/receive email when the are numbers in the domain name of sender/recipient.

     

    I have had to turn MTA off as a result this morning whilst they investigate.
