search the archives
and see    /etc/MailScanner/rules/*


eg.
not tested and no guarantee.
please correct me if i am wrong i have no great experiences with rules.
i prefer [tab] as delimiter in all rules


/etc/MailScanner/MailScanner.conf
##Filename Rules = %etc-dir%/filename.rules.conf
Filename Rules = %etc-dir%/filename.rules


/etc/MailScanner/filename.rules
FromOrTo:    user1 at sld.tld    %etc-dir%/rules/user.conf
FromOrTo:    user2 at sld.tld    %etc-dir%/rules/user.conf
FromOrTo:    default        %etc-dir%/filename.rules.conf


/etc/MailScanner/rules/user.conf
allow   \.zip$   -   -


--------
jump to  "filename.rules"
if  user[12]@sld.tld"  go to  "user.conf"
zip is allowed
default go to  "filename.rules.conf"
-------


restart / reload mailscanner
# service MailScanner restart
check the logs
# tail -f /var/log/maillog
and test it
