[OpenIndiana-discuss] retrieve mail with gnus but sort with procmail?

[Harry]

I had a big accident brought on by deep seated stupidity.  Lost my
whole OS and years of mail/news

So starting over and find my usage of fetchmail for pop3 retreival no
longer works.  So turned to gnus for that chore... find it works fine
but I don't see a way to run the mail thru procmail (what I've done in
the past using fetchmail).

I don't really want to learn all about fancy splitting unless I really
have to. I have a procmail setup developed over 20 yrs use that would
probably take a good while to duplicate or come close with `fancy
splitting', assuming I could evenn learn how to use it.  So asking
first if there is some slick way to push mail thru procmail with gnus?

And in case someone has the time or interest in helping, I am
including the fetchmail error at the end in case any of you are
fetchmail users and may recognize the problem.

Looks like fetchmail asked for STLS ... And pop.newsguy.com  wasn't
having it?


~/.fetchmailrc

poll pop.newsguy.com  proto POP3 user reader    password SECRET

mda "/usr/bin/procmail -f %F -d %T";

`Password' is actually in plain text and just munged for posting.

PS: This same .fetchmailrc file has worked for years against the same
pop server used on the Debian OS I trashed and inadvertently deleted.

Now in use on new install of ubuntu-20.10 and throwing the error shown
