We are having a problem where e-mail is not being delivered to addresses outside
our domain. I have narrowed down the problem to the e-mail headers that RT
generates. But I am clueless as to why this is a
problem.</FONT></SPAN></DIV>

We are an all-Windows shop, except for one ubuntu 8.10 server that runs RT 3.8
under Apache 2. For mail, it uses Postfix, and routes all mail to our
local Exchange server (Exchange 2003 under Windows Server 2000). For
e-mail that RT sends to recipients inside our domain, it all works well.
But we have some contractors who need to receive e-mail from RT on certain
events, and these contractors have addresses outside our network. But the
mail is never delivered.</FONT></SPAN></DIV>

After much experimentation, I narrowed the problem down to the
"Content-Transfer-Encoding: 8bit" header. If that header is present,
e-mail does not get delivered outside our network (e.g. to gmail.com, yahoo.com,
anywhere); if that header is absent, e-mail goes through
fine.</FONT></SPAN></DIV>

syslog tells me nothing useful: No matter what, it reports "mail queued for
delivery", which I presume is coming from the Exchange
server.</FONT></SPAN></DIV>

Now, I know this is not an RT problem, because I reproduced the problem
consistently at the ubuntu command line by manually invoking sendmail. But
a) I wonder if that header is required by RT, or if an alternative (base64?)
could be used instead; and b) Maybe I'll get lucky and someone on the list will
know a solution anyhow.</FONT></SPAN></DIV>
