550 Administrative prohibition

IT-ServerAOS

one customer Complains that his Emails doent reach our Employees.

 

user@ourdomain.com SMTP error from remote mail server after end of data: host host.ourdomain.com [IP-of-our-UTM]: 550 Administrative prohibition

 

We have a lot of communication that works fine and I don't want to unblock stuff just because they don't have their stuff configured correctly.

I wouldn't even know what to unblock since this error doesn't say whats wrong. the UTM can unblock so much:

RBL checks / RDNS/Helo checks / Antispam checking / Expression blocking / Greylisting / BATV / SPF check

 

I don't wont to open them all.

Does someone know what of this I need to skip to make it work and what I can tell them to fix. because I don't want to bother around with the other party long.

 

Thanks A lot

Michael

    Hey Michael.

    You need to check UTM's SMTP log and/or Mail Manager to identify why the message is being blocked and create exceptions accordingly.

    If you need help identifying the reason, provide us with the logs from the blocked message and screenshots from your mail manager.

    Regards - Giovani

    Michael, also, please show an IP like 88.x.y.123 instead of IP-of-our-UTM as that makes the "picture" easier to see.  Include all of the log lines related to an email that your UTM rejected - if the includes lines related to other emails, that's not a problem.

    Cheers - Bob
