problem with send-hooks

[Per Carlson <lists@xxxxxxxxxx>]

hi.

i've tried to set the From: header based on whom i send a email to
using send-hooks. what puzzels me that the hooks seams to work
partly, but not fully.

here is my (relevant) .muttrc:

+++

set from="Foo <foo@xxxxxxxxxxx>"

send-hook . \
       set signature=.sig_foo; \
       set from="Foo <foo@xxxxxxxxxxx>"

send-hook '~t "(user1|user2|user3)@.*"' \
      set signature=.sig_bar; \
      set from="Bar <bar@xxxxxxxxxxx>"

+++

when componing emails, the signature is correctly choosen, but the
From: header does always show "Bar <bar@xxxxxxxxxxx>". so, of some
reason does the regexp part work, but i can't understand why the
"set from=" part doesn't.

i've tried replacing "set from=" with "my_hdr From: ", switching
the order of "set sig..." and "set from", but that didn't help at
all...

reading the mutt manual didn't enlight me either. 

btw, is running mutt 1.5.9i.
