Anyway, until today I happily faked lots of "from" address. But today I sent 2 messages - one of them was to a fellow Spamgourmet user - and got this:
After sending a message to a non Spamgourmet user:

... while talking to *non_spamgourmet_server*.:

After sending a message to a fellow Spamgourmet user:

... while talking to gourmet.spamgourmet.com.:
>>> MAIL From:<>
<<< 553 5.3.0 Message from *myIP* rejected **** see http://cbl.abuseat.org/lookup.cgi?ip= *myIP*
501 5.6.0 Data format error
Now, *myIP* happens to be a shared IP (well, it saves me $1 a month) so I don't think it's my fault.
BTW, what's with the space in "ip= *myIP*"?
Anyway, here's the catch - in the "What's New" section you admitted you started using this CBL service, but my messages are NON reply masking OUTGOING messages, so how come Spamgourmet was involved in both messages (it should have only been involved with the message to the fellow user)?! Is there a chance the other server also uses CBL? What are the odds to send messages for years without crossing paths with CBL and then cross paths with it twice in the span of 5 minutes...?
