Here it is. -K

Question 4.12:
..............

   The number of total messages in a group which Gnus  displays in
group buffer is by far to high, especially in  mail groups. Is this a
bug?

   Answer:

   No, that's a matter of design of Gnus, fixing this would  mean
reimplementation of major parts of Gnus'  back ends. Gnus thinks
"highest-article-number -  lowest-article-number =
total-number-of-articles". This  works OK for Usenet groups, but if you
delete and move  many messages in mail groups, this fails. To cure the
symptom, enter the group via `C-u RET'  (this makes Gnus get all
messages), then  hit `M P b' to mark all messages and  then say `B m
name.of.group' to move  all messages to the group they have been in
before, they  get new message numbers in this process and the count is
right again (until you delete and move your mail to other  groups
again).
