Dear all,
we have unfortunately a problem because of the blokierung of the server IP address, however this is not listed according to SpamCop Blocking List.
Here is the error message:
550 5.7.1 Service unavailable; client [144.76.110.144] blocked using
bl.spamcop.net (in reply to RCPT TO command
How can this problem be solved?
LG Design2enjoy
