SMTP error from remote mail server after initial connection:
550 rejected because 217.155.197.248 is listed in bl.spamcop.net
spamcop.net had - maybe still has - a problem, which caused the same
problem on the linux-audio-user list. If it isn't solved yet, it should
be very shortly apparently. The LAU list temporarily deactivated the
spamcop blacklisting yesterday.
Best wishes,
