Error after postfix upgrade

Quoting Julian Field <MailScanner at ecs.soton.ac.uk>:

Here's the (admittedly stupid) thing I did to get email working again.

I downloaded the latest version of MailScanner and compared the  
Postfix.pm file.  There's a comment there that specifically addresses  
this situation, so I checked the other differences and decided to just  
copy the new Postfix.pm file over the old one. Mail is working, though  
I get some different errors that I've worked around.

I was trying to stay within Ubuntu's package management. I knew I  
wouldn't have the latest and greatest code, but I at least thought  
they wouldn't upgrade a package without upgrading other related  
packages (or at least keeping them compatible). Obviously, I was wrong.

The "right" thing to do would probably be to remove the MailScanner  
package and install from the latest tarball from the MailScanner site,  
but I had really hoped to stick with the distribution's package  
manager :-(

Thanks, everybody, for the tips.
