but in my case , we have result actually looks like this:
250-mail.example.com Hello there [X.X.X.X]250 STARTTLS
any help please .
Hi ZIDANE ISLAM
Please make sure, WAN zone can able to access SMTP Relay
- XG v17 Technician Certificate -
yes the SMTP Relay it's enabled for my configuration ,
To support Auth, MTA on Sophos XG need to speak (AD, LDAP , ecc) with authentication services that host mailbox (Exchange server [AD], Zimbra [LDAP], etc).
Actually Sophos XG can not support SMTP AUTH to accept email from external users.
