[rt-users] $RT::MailCommmand = smtp

Wed Aug 8 11:22:10 EDT 2001

Hi Steve,
The real problem is not about "nobody", it's really on the domain name.
Try sending an e-mail with the "MAIL FROM:" set to
<steve at dummy.inet-technologies.com> to anything at ubp.ch (a private
bank....).
Your mail will be rejected because "dummy.inet-technologies.com" is not
known to the DNS...
And if your sendmail is configured to set "localhost", it's even worst I
think ;-)))

It's just that some mail servers, to avoid spamming, check that the
"MAIL FROM:" adress has a domain name known on DNS.

Cheers
Rafael

Hi Rafael,
Well i don't really think it's a problem. A lot of our mailing scripts
use sendmail and yes its true, in the header it's always
'apache-user'@localhost for example, but we don't use nobody for RT.  To
not use nobody, what we do is we run another apache configured on
another port with user rt. RT process are big, and it give us the
opportunity to run a standard apache server 80 on this machine that
don;t ned to handle RT for each external requests not related to RT. (I
know its bad to not use nobody but the machine is very
secure)
