553 errors

[Shannon @ shaw]

Yeah, I know that too. That was kind of my point... You can't just browse 
through the log files because it's full of those and it'll just put you to 
sleep.
When I parsed maillog for the domain that couldn't send me mail I didn't 
find any entries.
I can grep for "Rejected" and find plenty
I can grep for "google" and find plenty

I suspect that particular domain uses "gmail for business" (or at least, the 
particular user has her outgoing server set for a gmail server) and that's 
what's causing the rejection. - But, it doesn't happen every time. At least 
not to mailing-list messages from that domain. Only the messages from that 
particular user (that I know of).

I'll figure it out, I just thought someone might know of a particular issue 
with companies that use google's mail services.
Of course, we may be the only three that are still subscribed to this list 
;-)

Well, the line you listed below is a block from spamhaus.org.  You are using 
that RBL to block spam and it has received spam from the originating IP 
address.  Its not a misconfiguration unless you didn't want spamhaus 
blocking.  If you want to retain spamhaus blocking then you need to tell the 
originator to contact the admin's at the originating MTA to have them fix 
the problem that cause the blockage by spamhaus.
