Delivery status notification, MTA-BLOCKED

Post by Woodd »

We had 3 domain aliases configured, i.e.
domain - main
domain2 - alias
domain3 - alias
domain4 - alias

Due to the transition to the main domain2, the domain name was changed in the settings, i.e. it became like this:
domain - alias
domain2 - main
domain3 - alias
domain4 - alias

Domain name change was made by these commands

Code: Select all

zmprov mcf zimbraDefaultDomainName domain2
zmprov -l rd domain domain2
Everything went well, the letters are delivered, but when sending letters to the domain (alias), a delivery report is received:
Your message WAS SUCCESSFULLY RELAYED to:
<user @ domain>


The message WAS NOT relayed to:
<"" @ domain2>: [[127.0.0.1]: 10025] sai
501 5.1.3 id = 19250-05 - rejected by next-hop mta on relaying, from mta (smtp127.0.0.1]: 10025): 501 5.1.3 bad recipient address syntax
Such reports come both when sending internal mail and external mail.
Why are these reports coming? And how can you turn them off?
