Dear all,
I've just updated an SME 5.6 with the latest update6 (it was already updated up to update3 I believe).
After doing this every user on the network receives the following error message when trying to send or receive mail (oulook 2000 mail client, pop3):
server response: 451 message refused by mail server (account: ### account name ###' SMTP server '### mail server ###' error number Ox8OOccc6a
It's seems to be a very obscure message since little (usefull) is to be found on the Internet.
I cannot find anything useful in the log files either ...
HELP!
