Recipient address rejected: unverified address / Recipient address rejected: Access denied

Since the update of ISPConfig 3.2.7p1 to 3.2.8p2 I have trouble receiving some mails; the error always looks like:

Code:

postfix/smtpd[xxx]: NOQUEUE: reject: RCPT from mail.server.tld[xxx.xxx.xxx.xxx]: 450 4.1.1 <[email protected]>: Recipient address rejected: unverified address: host 127.0.0.1[127.0.0.1] said: 554 5.7.1 <[email protected]>: Recipient address rejected: Access denied (in reply to RCPT TO command); from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.server.tld>

What should I check?

 

Yes, of course, master.cf also contains the 2 lines to overwrite address_verify_virtual_transport and address_verify_transport_maps from main.cf.
I have however modified inet_interfaces in main.cf and listen in dovecot.conf to only include 127.0.0.1 and the ip addresses of the mail (smtp, pop3, ...) hosts.

 

Yes, I have
* Set inet_interfaces = all in main.cf (instead of only a few IPs)
* Set listen = * in dovecot.conf (instead of only a few IPs)
I also tried to
* Remove address_verify_virtual_transport and address_verify_transport_maps from main.cf
Some mails got through. Some didn't (as far as I can see), I think the last action had most impact, but I undid that one again as I want to use all ISPConfig features.

 

@till Any clue?

 

It looks like removing address_verify_virtual_transport and address_verify_transport_maps from main.cf solved the problem, but is that a solution?
