There isn't, at least not within procmail. You have to write something
special for each case. For your Lyris example [folding mine to appease
MSOE],
| List-Unsubscribe:
<mailto:leave-isp-colo-762587K(_at_)lists(_dot_)isp-lists(_dot_)com>
| List-Unsubscribe:\
<mailto:leave-isp-webhosting-762586E(_at_)lists(_dot_)isp-lists(_dot_)com>
| List-Unsubscribe:
<mailto:leave-isp-equipment-458649T(_at_)lists(_dot_)isp-lists(_dot_)com>
I'd write [condition wrapped to appease MSOE]:
:0:
* ^List-Unsubscribe:.*:leave-isp-\/\
(colo|webhosting|equipment)-[^ ]+@([^ ]+\.)?isp-lists\.com>
* MATCH ?? ^\/[^(_at_)]+
isp-$MATCH
or a little less efficiently,
:0:
* ^List-.*\.isp-lists\.com>$
* ^List-Unsubscribe:.*:leave-isp-\/(colo|webhosting|equipment)
$MATCH
and every time I joined another list at that host, I'd add its name and
delete names of lists I had unsubbed from.
Something I wonder: suppose I belonged to all those lists and also to the
colonoscopies list. Then
leave-isp-\/(colo(noscopies)?|webhosting|equipment)
would match each correctly, because matching to the right of \/ is greedy.
But what would happen if I used
leave-isp-\/(colo|colonoscopies|webhosting|equipment)
instead? Would messages from the colonoscopies list be matched to "colo"
instead? (And a big public merry Christmas to the first ten people who tell
me where I can stick messages from the colonoscopies list.)
