59736 - Sending mail through a child process is not supported.

Status: RESOLVED DUPLICATE of bug 93822

(MailNews Core :: Networking: SMTP, enhancement, P3)

Description

[Pavel Roskin]

Other mail clients, e.g. Pine, support sending mail by invoking sendmail or
other MTA rather that by connecting them over TCP/IP.

It may be needed if sendmail or other MTA is not running as daemon or it refuses
to relay mail or access to the port 25 outside the LAN is blocked by firewall.

Users may want to run sendmail over ssh or Kerberos rsh on machines where they
have accounts rather than to feed their mail to broken sendmails without proper
DNS records within the firewall.

[(not reading, please use [e-mail] instead)]

it's an interesting idea.  instead of going through the smtp protocol, we'd just
exec a command and pass it the file we write to /tmp.

if we ever did this, any changes to the ui would have to be UNIX specific, just
like the eventual movemail UI will be.

marking enhancement.

pavel, I don't expect we'd get to this feature any time soon.

FWIW, I've used this to create and send test messages. You just create the
entire message, including headers, and do something like
   cat message.txt |sendmail -t -U
or
   msg-prog |sendmail -t -U
or even a perl script. It's just piping.
