If you were expecting an email from me, or if you tried to subscribe to the fglrx mailing list and didn’t get a confirmation request, here’s the most likely reason:
SMTP protocol diagnostic: 553 5.3.0 Error:554 – Mail from 212.216.176.141 refused – See http://dnsbl.sorbs.net
212.216.176.141 is one of the SMTP servers of my ISP, Tin.it, which is most definitely not spammer-friendly. It’s been listed for a while — I don’t know if Tin.it adminstrators are unaware of this issue or if the folks at SORBS are not removing it for whatever reason, but unfortunately, there’s nothing I can do.
