Hello,

This morning a did some add in whitelist and blacklist, now, all mail are blocked with this message :

1DC52401090D: to=<destination@domain.tld>, relay=127.0.0.1[127.0.0.1]:10024, delay=3,
delays=0.01/0/0.06/2.9, dsn=4.4.0, status=deferred (host 127.0.0.1[127.0.0.1]
said: 451 4.4.0 detected undelivered mail to <destination@domain.tld> (in reply to end
of DATA command))

Of course, destination@domain.tld is there to mask the real email address.

What can I do ?

Thank.

Michel

Found ! I reply to myself !

There was an error in another list. Tried to block a word in the Subject but I did some mistake in writing the rule.

Sorry for the noise.
