Mails getting delayed and failing

PepijnDeneut
Hello,

We have complaints that we can't receive mails from different parties.
These are mostly small parties, outlook.com, gmail.com ect works fine.
They get errors like:#550 4.4.7 QUEUE.Expired; message expired ##
The problem is we don't see anything in the smtp log.
Anyone has an idea?

Thanks

    My Nederlands is a bit rusty, but all of your things look good to me.  Maybe not for the company trying to send you mail.  Search in your SMTP Proxy log for 81.83.2.122 and I bet you can find out why their emails were not accepted.  Any luck there?

    Cheers - Bob
