For a summary of recent-past emails about this, see: 
http://dovecot.org/list/dovecot/2007-November/027148.html

To make the script in this email work for both POP3 and IMAP:

$ cat /root/dovecot-login.sh
#!/bin/sh
PROTO=`basename $0`
echo $PROTO > /var/spool/lastlogin/$UID
exec /usr/libexec/dovecot/$PROTO

$ ln -s /root/dovecot-login.sh /root/imap
$ ln -s /root/dovecot-login.sh /root/pop3

In dovecot.conf:

protocol imap {
...
mail_executable = /root/imap
...
}

protocol pop3 {
...
mail_executable = /root/pop3
...
}
