Okay, first of all I gave you a bum regexp because I didn't test it
first, my bad! The colon shouldn't be in there, that's blocking it from
matching the group name. There's no reason for that bit anyway, just
"^nnimap" should be sufficient.

Second of all, even with a good regexp, it won't return
the correct parameter, apparently because of a bug in the code. I'll
open a bug report for this.

No worries, this is the "help users" group, besides which there's at
least one real bug in here.

Yes, all of these methods (setting `gnus-parameters', setting
`nnmail-expiry-wait' globally, setting `nnmail-expiry-wait' as a server
parameter) should work. Possibly you've done something funny somewhere,
but the fact that the first method has already uncovered a bug makes me
suspicious of the rest of it. I'll ask on gnus.general (I feel like
there's more eyes on that group) what other people are using, and make
sure something works.
