When sending mail to my server some users get rejected with this error:
Mail delivery failed: returning message to sender
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
SMTP error from remote mail server after RCPT TO:<email@example.com>:
host XX.XXX.62.110 [XX.XXX.62.110]: 504 5.5.2 <XX.XXX.62.73>:

Any clue to fix this? What is it on my server who rejects this? (any way to bypass it?)
