Hi Marco.Marco,

550-Verification failed for <marco@xxxxx.com> 550-The mail server could not deliver mail to marco@xxxxxcom. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)

"550 - Verification failed" - issues are mostly DNS - depending misconfigurations.

Consider to use sites like for example:

mxtoolbox.com
dnswatch.info
mail-tester.com
dkimcore.org/tools/
dmarcian.com/dmarc-inspector
checktls.com​

... to investigate possible misconfigurations on your own and provide informations from their tests.
In addition, it would really help to include as well configuration files for investigations, to avoid guessings from people willing to help you.

Hi Marco.Marco,

Investigations for "postfix/main.cf"

mynetworks = , 185.81.0.73/32

Here you missed the "localhost" - setting:

mynetworks = , 127.0.0.0/8 [::1]/128 185.81.0.73/32

You have missing configuration settings in your "main.cf" ... did you shorten the configuration file?
Pls. include as well the corresponding "master.cf" for further investigations.

Are you adding investigations from the above mentioned links? If not, pls. consider to provide informations about "marco@xxxx.com", because we can't guess the domain name and anonymous informations can't be investigated with facts.


Did you already try the "Plesk repair utility" as well, to solve your issue?

If not, pls. consider to provide informations about "marco@xxxx.com", because we can't guess the domain name and anonymous informations can't be investigated with facts.

Did you already try the "Plesk repair utility" as well, to solve your issue?
