Just for the general knowledge pool, it seems that relays.osirusoft.com is offline, I just dropped a few thousand messages for my customers with the error:
554 Service unavailable; [216.82.69.69] blocked using
relays.osirusoft.com, reason: Please stop using
relays.osirusoft.com
and relays.osirusoft.com now resolves to a mozilla.org site.
This is linux relevent as the subject of spam blocking has come up a few
times, and specifically server side rbl blocking..
Cheers, Chris, I hate spam, Hellyar
