The masquerading options are for a different purpose. I'm glad you got it sorted out.
Although I'm able to send mail to most people without a problem using smarthost, I still have a few that bounce back with errors like: Your message was rejected by mail.lance.com for the following reason:
Service unavailable; Client host [cdptpa-omtalb.mail.rr.com] blocked by zen.spamhaus.org; http://www.spamhaus.org/query/bl?ip=70.62.90.185
I'm using the smarthost server that I should be using according to the information: define(`SMART_HOST',`smtp-server.carolina.rr.com')dnl
Although I'm in a residential IP range, my connection is Business Class, so sending smtp mail is not restricted (at least contractually).
Why would I still have this problem if I'm using smarthost? Is there a way to resolve it?
Thanks, James
