On reviewing the thread several times, I see what you mean about the message being local. But if you look at the bounce error, it appears to be copied from the mailer daemon bounce notice not from the output of `mail -v' >>> MAIL From:<jorge@xxxxxxxxxxxxxx> SIZE=334 AUTH=<> <<< 553 satyr.bogus.jl does not exist 501 5.6.0 Data format error I'm still thinking its his smart host doing the rejection and error. Hope not to be clouding things up here.... and for Jorge's benefit let me state that I am far from expert in sendmail matters. > I would like to see what Jorge has in his /etc/hosts file, for localhost > and satyr.bogus.jl. Yes, that would be good. Harry wrote: >> It is unable to lookup his bogus fqdn. And unless he masquerades as >> an domain that machine knows, it will not let him relay.

What do you mean by `through their customers MTA'? Why would a customers MTA be acting as smart_host? I'm either really missing the big picture or it is Verizons own smtp machine that is acting as Smart_host to Jorge's outgoing sendmail processes. And that it requires incoming mails source IP to be resolvable is not unusual. It happens to me even in domains unrelated to my ISP, if I don't either masqerade as my ISP or use genericstables to get the same sort of result. That is that, "envelope From" appear to be from a resolvable host. I'm very curious why masquerading as `jorge.cc' would make things work. I'm wondering if that setting ever made it into sendmail.cf and if sendmail was restarted thereafter.
