[Mailman-Developers] Mailman not delivering the mail

[Michael McLay]

The subscribe script execute and the Web page that is returned says
a message will be sent to the subscriber, but no message arrives.
I think something is wrong with gid or uid.  By adding an intentional
bug in Mailman/mm_utils.py the attached trace was triggered just after 
msg.GetSender() was called.  Here's the bug that was added:

	import smtplib
	sender = msg.GetSender()
	findbug

The debugging code that was added shows that the script is being
executed as nobody. Am I correct in assuming that the mailer won't
send out a message from nobody because nobody is not a trusted user?

  uid   65534   (nobody)
  euid  65534   (nobody)
  gid   55	(mailman)
  egid  50	(wwwcgi)  - a group set up for cgi scripts.

I also was curious about the wwwcgi egid.  This is the gid setting
used inside the httpd configuration, but when the subscribe cgi script 
create the data/pending_subscriptions.db the group is set to mailman.

I'm confused about what the settings of all these things should be.  

I also found the layers used to send out the mail messages to be 
puzzling.  Why the trip from maillist -> MailList -> mm_deliver ->
Deliverer - > DeliverToUser -> mm_utils -> DeliverToUser.  Why so much 
indirection?
