Subject: ezmlm-idx, "Received:" line-format and listserv suffix

Hi,

first let me notice that ezmlm-browse seems currently unusable
(eg:
http://lists.untroubled.org/?list=ezmlm&cmd=threadindex&month=201304&threadid=ijeioimgammohldkbmofshows
that
"<type 'exceptions.IndexError>"

Secondly, note that the confirmation link in the subscription email is
wrong.

Then the core-issue:
I recently found to have trouble with ezmlm-archive while archiving emails
from Yahoo Groups
(after using yahoo2mbox-0.25.pl and some other trickery) :
Message was :
> Old format or corrupted index. Run ezmlm-idx! (#5.3.0)

It always happened on similar lines of the same indexes.
Eg:
this one was valid :
> 12: nigndcggknndaohnnhpc AAA
>        9 Sep 1999 20:01:06 -0000;ndjacphkfldlldkmglai BBB
but this one was failing (found by strac'ing)
> 13: bffikoegbfkopjbigpba CCC
>        by qk; 13 Sep 1999 21:51:50 -0000;gejcgihhokjofdhalfoj DDD

Obviously this " by qk;"** is the culprit.
Digging further, I found this kind of lines in the original emails :
> Received: (listserv 1.262); by qk; 30 Sep 1999 21:26:11 -0000
> Received: (listserv 1.276); by a1; 05 Nov 1999 19:06:18 -0000

These were emails typically received by Yahoo! during the 1999/2000 period.
My guess is that listserv was buggy at that time and not conforming to the
RFC but
I'm not sure about this.
So if someone more knowledgeable is sure about the opposite, then ezmlm-idx
should
try to be smarter in parsing this header field. Otherwise I hope this email
could help
someone facing the same issue, especially since more people will want to
run away from
Yahoo groups these days.


best regards
