I use both. Exim handles the RBLs, ExiScan does the initial virus
checks, removes file types I never want to see (exe, com, etc)
and MailScanner does the anti-spam (SpamAssassin), defanging, and
detailed file removal.
Mailscanner allows you to block files by regex so you can
deny+delete wendy.zip and allow *.zip later. MailScanner allows
you to block on file type so you can block Unix ELF files,
windows/dos executables even if they have a different extension
(and windows will execute x.exe even if it has been renamed
x.mmm)
MailScanner will defang various types of emails, for instance
remove I-Frame sections, forms, Code Base sections, handles TNEF
and various other potentially dangerous malformations
MailScanner also has a fairly robust rules based configuration
for flexibility as well.
In Short, ExiScan is a good front end product for handling simple
obvious things that there is no reason you would ever want to see
and MailScanner is far more flexible and thorough backend product
that does it's job very, very well and let's Exim get back to
what it does better than anything.
