Sendmail, bat book and Arrrggggghh!

Hi All,

I am trying to configure sendmail on a RH 6.1 box, and it will send mail
out, but it keeps getting bounced: the error I get is:

----- The following addresses had permanent fatal errors -----
jackryan@azbiz.net

----- Transcript of session follows -----
... while talking to warp.azbiz.net.:
>>> MAIL From:<sean@yaqui.we-web.com> SIZE=303
<<< 501 <sean@yaqui.we-web.com>... Sender domain must exist
501 jackryan@azbiz.net... Data format error

I am thinking that is because the address is yaqui.we-web.com and not
we-web.com. Is this a correct assumption? I looked in the bat book
(Arrrgggh!) but I didn't see anyplace to change it.

Help!? Pleeze!!!

Thanks,
Sean
