account-hook with same imap server but different authentication

[spekul <spekul@xxxxxxxxxxxxx>]

hello list,

is it possible to use two different account hooks for the same imap  
server but with different login credentials?

when looking at the definition of an account hook at http://wiki.mutt.org/?MuttGuide/Hooks 
, it is defined as:

account-hook path-regexp command

after having gone through http://wiki.mutt.org/?MuttGuide/UseIMAP, it  
seems like path-regexp is not just a descriptive pattern for making it  
possible for mutt to reference different accounts. instead it is the  
server url the hooked parameters given afterwards are valid for.

but how should i reference two accounts for one and the same server  
for different mailboxes with this? thanks for some enlightenment  
there, maybe its possible but i have overseen something somewhere.  
what i would like to do is something like the following, what seems to  
be impossible to me since path-regexp is the same in both cases:

account-hook imaps://server1.com 'set folder=imaps://server1.com  
imap_user=user1 imap_pass=pass1 "
account-hook imaps://server1.com 'set folder=imaps://server1.com  
imap_user=user2 imap_pass=pass2

thanks for your help, regards,

frank
