[Dovecot] post-login scripting using PHP

[Maciej Uhlig]

I'd like to write post-login script using PHP. I noticed every shell 
post-login script ends with: exec "$@", which effectively executes 
dovecot's script-login.

However, while I try to do the same (?) in PHP: $prog = $argv[1]; exec 
("$prog"); it doesn't work. The client timeouts, dovecot (2.0.6) says 
"Disconnected for inactivity".

May be I don't clearly see the way post-login scripting should work. Any 
hint to make it done?
