gpg - .muttrc vs. .mutt.personal

[Michal Hajek]

Hello, can anyone please help to solve this problem :
I have in my .muttrc
set pgp-autosign
source .mutt.personal

but, I would like for some people, who wish not to receive signed mail,
to have 
unset pgp-autosign.
I have put 
send-hook this.peoplewhodontlikesig'[EMAIL PROTECTED] "unset pgp-autosign"

But, this seems to overide my .muttrc, since now mutt behaves so, that
no one ge
ts signed mail by default.
Any ideas ?
Thanks in advance... Michal Hajek
