You can do this (and many other things) through Post-Login Scripting:
http://wiki.dovecot.org/PostLoginScripting

See in particular “Last-login tracking”:
http://wiki.dovecot.org/PostLoginScripting#line-20


A simple example for your specific request:

In /etc/dovecot/dovecot.conf:

protocol pop3 {
# [etc.]
mail_executable = /full/path/to/custom-pop3.sh


Then, in custom-pop3.sh: (which needs to be chmod +x)

#!/bin/sh
touch /var/mail/.pop.$USER
exec /usr/libexec/dovecot/pop3

Best,
