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!
