FC3 Gnu/Linux i686 kernel 2.6.9-1.667.
I don't know if this a "peculiar" problem or not, but to start, I have an
account with GTE, and I have a DSL with SBC, and I have a domain
but no static IP so my domain sits on a friends machine, but he is NOT
my ISP, so here is the problem.
I can send from firstname.lastname@example.org to anyone, I can not send from
email@example.com to anyone but my friend (hosting my domain).
the error message I get is: 5.7.1 <firstname.lastname@example.org>...Relaying
denied. IP name lookup failed [my dynamic IP].
But, if I telnet hostname 25 and do
mail from: email@example.com
rcpt to: firstname.lastname@example.org
it delivers succesfully.
It used to work fine for most recipients (always had problems sending to
AOL and CS (AOL subsid).
I seem to be a little slow learning Linux, so don't be too hard on me ;=)
