I solved my problem: I'd also upgraded smail and the new version wasn't prodding my ISP. I needed to reconfigure Smail using the smailconfig --force option. The default method of starting from inetd didn't work for me: I now have a smail daemon running and it works perfectly. Hope this helps anyone else.
