Issue when receiving Mails from Company with more than 1 MX-record

DCOM-DW
hi everybody!

could someone confirm an issue on an utm9 virtual-appliance while receiving mails from a company with more than ONE mx-record defined (f.e.: bmwgroup.com)?

Model: ASG Software
Firmware version: 9.206-35
Pattern version: 66789

there are absolutely no log's about the mails found in the SMTP-protcoll in mailmanager.
whether they are junke'd or received or something else ...



thx!

    hi,

    well @ BAlfson - since we use the utm as mailsecurity only there ist no NAT configured!
    @ Brucek: of course, we do STRICT RDNS & GREYLISTIING but we wouldn't check these "filters" off!

    the isseus startet first with the last update of the utm.


    thx!

    Configure an exception for that one email domain, no need to switch those features off wholesale.
