1) iRedMail won't send non-delivery notification with these mail headers.
2) If you configure the Outlook to perform SMTP login before sending email, then client FQDN check will be bypassed.
So this is not rejected by iRedMail at all. Please check whether it was connecting to a different mail server while you sending mail from domain2.com to domain1.com, maybe caused by DNS cache in local network. For example, check DNS response with command "nslookup", "dig", etc.
domain2.com domain1.com NOK
Hello,
I have set up a iRedMail server on a new vanilla Ubuntu Server.
The hostname (fqdn) is mail.domain1.com
I have set up 2 domains on it: domain1.com and domain2.com
When i user Roundcube everything works great, but if i user Outlook from different locations with different IPs i have the following situation:
Sender Receiver Result
domain1.com domain1.com ok
domain2.com domain2.com ok
domain1.com domain2.com ok
domain2.com domain1.com NOK
domain2.com google.com ok

The following recipient(s) cannot be reached:
User (user@domain1.com) on 1/30/2013 1:21 PM
Server error: '554 5.7.1 <user@domain1.com>: Recipient address rejected: Invalid HELO/EHLO; Must be a FQDN or an address literal, not 'ALEXANDRAPC''
User2 (user2@domain1.com) on 1/30/2013 1:21 PM
Server error: '554 5.7.1 <user2@domain1.com>: Recipient address rejected: Invalid HELO/EHLO; Must be a FQDN or an address literal, not 'ALEXANDRAPC''
ALEXANDRAPC is the computername of the client.
Does anyone have knowledge how to solve this?
Thank you very much!
BR,
Horia
