have a (stupid) question …
i started to work in a company with a Axigen Mailserver
and this will be the first time I gonna integrate a new domain on it
i added a MX Record like: mail.domain.com to the Domain DNS
and a testmail reached the Axigen Mailserver
but two things happened …
the writer received: SMTP error from remote server for MAIL FROM command, host: mail.domain.com (12.345.67.890) reason: 550 rejected by filter
and on the Axigen Mailserver I found this in the log: >> 503 No recipient accepted for this mail
what are the correct DNS records to make it work ?
I gonna ask, because I tried a few other things that I found on google
but no success yet
For sure there is a misunderstanding as a message is either accepted (so it is locally delivered) OR rejected with a 5xx code. As it seems you are not ready to share any useful information regarding your domain my suggestion is to open a support ticket so you could receive targeted recommendations for your specific installation.
In your example you have two 5xx codes (550 and 503) and for sure a message could not have 2 reject codes.
