MailSecurity: Exception for Maximum Message Size
The maximum message size is a global parameter for MailSecurity but some users/groups need to send/receive bigger email messages. There is no way to allow only sepecific users/groups to do that except allowing that for all users.
A possible way is to implement it at exceptions for MailSecurity.

Volker, can't your mail server do that? Usually, I configure the maximum as the maximum configured in the mail server, and then trust the mail server admin to manage the individual limits.
