"550 5.7.1 unable to relay for XXX" error in lumisoft Mail Server

This error occurs when I explore lumisoft Mail ServerSource codeIn the process, it severely plagued me for a week.

Fortunately, I am still very resilient to find the cause and solution. Although I had a lot of detours while searching for answers, I finally found the answer with my persistent efforts, I hope it will be helpful to anyone who has encountered the same problem as me.

Problem: When the lumisoft mail server is started, "550 5.7.1 unable to relay for XXX" error will occur when you use webmail to send emails. The message "queued for delivery" is displayed when you send an email using the command line ".

Cause: SMTP in my IIS is started by default and occupies port 25, leading to the above problem.

Solution: Disable the SMTP virtual server in IIS and restart the lumisoft mail server.

Ivx answer

> 550 5.7.1 unable to relay
If you get this, then you run non ls mail server and you have not relay permission, probably iis smtp is running on port 25.

 

Ls SMTP is enabled by default, it probably conficts iis smtp and wont run.
You may have Andy count of SMTP servers in 1 computer as long listening IP: Port won't conflict. I really admire and thank ivx! Related Websites: http://www.lumisoft.ee/
