procmail, gnus and "new" mail groups

procmail, gnus and "new" mail groups

[Andreas Fuchs]

Hi,

When I receive an e-mail from a mailinglist, procmail filters it by some
headers (X-Loop, X-List etc.) into mboxes with the suffix ".in" in my
~/.procmail dir. This has worked really well together with gnus.

Now, when I recently joined a mailing list, gnus would refuse to put the
messages in the new .in file into a new group. I know for sure that it
has done so in the past, but I dunno when it stopped working (I'm using
a fairly recent cvs gnus).

Is this a bug? A new, (un)documented (I checked info node "Mail Source
Specifiers") feature?

TIA, regards,

What does "refuse" mean?  Gnus doesn't read the .in file? What is the
value of mail-sources?

Which version of gnus did the past refer to?

mail-sources=
((file :path "/home/asf/Mailbox"
       :plugged t)
 (directory :path "/home/asf/.procmail/"
            :suffix ".in"))

Yes, gnus doesn't read the .in file.

As I said, I don't really know, because I never joined any new mailing
lists recently. But AFAIR, gnus 5.8.7 (or was it .6?) did it right.

Sorry for being so fuzzy with version numbers, but I really don't
remember anymore.

According to your setting, Gnus gets the new mails from procmail
directory only when it is plugged.  Are you sure it is plugged?

It's funny that you mention this, because I stopped using the agent
about two weeks ago. So now, I start gnus with the "gnus" function
again, neither with gnus-unplugged, nor with gnus-plugged.

I assume that gnus is always plugged, then. Or isn't it?

Are you saying that Gnus fetches mail from, say, foo.in (because
nnml:foo exists) but not from bar.in (because nnml:bar does not
exist)?  What happens when you use `G m' to create the bar group
manually?  Does it work then?

Yes, that is absolutely correct.

Jup, it works then. Yet, I was still so used to getting the old behavior
that I assumed the mailing list software was at fault, and not my setup.

I think that this Gnus behavior is a bug.  Wonder if some guru might
find the problem...

I am not sure which command Andreas used to fetch new mails.  Due to a
hack of directory mail source, `3 g' or `M-g' might not fetch new
groups, but `g' should do.  Anyway, the following line might help.

    (setq nnmail-scan-directory-mail-source-once t)

Being the lazy bum that I am, I use the command that uses the fewest
keystrokes: "g" (-:

Hmm. Might just work. Before:

`nnmail-scan-directory-mail-source-once' is a variable declared in Lisp.
  -- loaded from "nnmail"

Value: nil

Documentation:
*If non-nil, scan all incoming procmail sorted mails once.
It scans low-level sorted spools even when not required.

After:
...
Value: nil
...

After "g"ing in the Group buffer, "F" tells me that there are now two
new mail groups. Yippie!

Now it works. I never changed this variable from the default. Could it
be that the default was changed? Why?

Again, thanks a lot.

To save time, Gnus only scans those .spool files whose correspondent
groups are requested, when `M-g' or `3 g'.  If
nnmail-scan-directory-mail-source-once is non nil, it force Gnus to
scan all existing .spool files like `g' does.
