[Mailman-Users] Unable to confirm subscription with outlook

[Darko Longin]

Thank you Mark,

That's fixed it... Im's surprised that Outlook/Exchange does not support
VERP but, really, I don't think I should be. 
It's a shame I'm having to disable it as all other (free) mailers worked
just fine. Ah well...

Again, thank you for the help

Absolutely. The subject "RE: Your confirmation is required to join the
some-internal-list mailing list"

Says you have "VERP_CONFIRMATIONS = Yes" in mm_cfg.py which produces
that subject in the confirmation e-mail and a From: address of the form

From: listname-request at example.com+<cookie>

Outlook/exchange is dropping/munging the "+<cookie>" part of the
address in the reply.

You can remove "VERP_CONFIRMATIONS = Yes" from mm_cfg.py which will
make the confirmation be

From: listname-request at example.com

with

Subject: confirm <cookie>

This format may work with outlook/exchange. You also may be able to
configure exchange to preserve the "+<cookie>" part of the address in
the reply.
