[Mailman-Users] Warning: I/O Error While Trying To Byte-Compile

Below, you suggested not to use postfix-to-mailman.py. 

What should I use if not this? My postfix master.cf file contains the
mailman MTA lines toward the bottom...

Mailman unix n n 2 pipe
	Flags=FR user=list
	${nexthop} ${user}

This seems to be making the server go crazy, tons of processes running
at once, bogging down the server. Commenting these lines out returns the
server to normal operation, but then in my mail.info log file, I have
tons of Mail Transport Agent not found.

Please help.

You clearly don't need qmail-to-mailman.py, and while Debian seems to
like postfix-to-mailman.py (which is not distributed even as
contributed source by the GNU Mailman project), I don't recommend it.

This is a Debian packaging issue. If you wish to install Debian's
Mailman package, you'll have to take this up with Debian.

If you download and install the 2.1.13 tarball from
<https://launchpad.net/mailman/2.1/2.1.13> or
<http://ftp.gnu.org/gnu/mailman/>, it will be less convenient, but we
can help you with any installation issues.
