please see http://www.spamhaus.org/query/bl?ip=80.229.179.189.

It looks like you're trying to send email direct from your PC, rather
than via Plusnet's email server, not many places will accept email from
IP blocks that are adsl or dialup (as that IP address indicates) and
especially if someone else within the same block has been sending spam
and got the block blacklisted.

If you configure thunderbird to use relay.plus.net you should be ok.

I suspect that relay.plus.net will be blocking his connection because a
machine on his IP appears on the blacklist. Whichever machine that is
may have been attempting to route email directly without going via
plusnet's SMTP server and thus managed to get onto the blacklist in the
first place.
