Migrate system: amavisd-new to mailscanner?

[Anthony Cartmell]

Hi folks,

I'm, currently, for my sins, helping www.ippimail.com to keep their  
systems going.

They are running old versions of Postfix with amavsid-new and clamd, which  
seems to work OK, but I'd be more comfortable with MailScanner than  
amavisd-new.

I use MailScanner with sendmail on my own servers, but Ippimail has  
usernames in a database (used for other things too), and I don't know how  
to get sendmail to use MySQL database for authentication. Is this  
possible?  Also his usernames contain "@" which sendmail can't handle  
AFAIK. Also some users have mail accounts in the form  
name at username.ippimail.com, just to add to the confusion.

So perhaps Postfix plus MailScanner might be OK? This would mean I could  
leave Postfix set up as it is, but replace amavisd-new with MailScanner,  
probably a simpler task?

Current OS is Fedora 5 (!) but they plan to move to CentOS soon.

Any advice on best options?

Cheers!

Anthony
