After the last updates errors with the mail accounts. It seems that when emails are sent they bounce and give an ip error. This happens at 8 vm.
Has anyone detected any of this?
Thank you
There was only a change to roundcube, not to exim itself, can you explain further?
Hello good morning.
The problem is the following:
When a client wants to send me an email, it appears that he is on a blacklist and returns the 550 error or that the email does not exist.
Sometimes it goes in, sometimes it doesn’t… and it’s random.
I paste a header from a return:
[email protected]
Remote Server returned ‘550 5.7.350 Remote server returned message detected as spam → 550 Rejected because 40.92.74.56 is in a black list at zen.spamhaus.org;Error: open resolver; DNSBL Error Code - Open/public resolver - The Spamhaus Project’
