You can try to implement this with Amavisd (with parameter "$banned_filename_re ="), ban all file types.

Thanks for the reply Zhang but how to implement it exactly?

When I go to /etc/amavis/conf.d/ i see alot of configuration files. Where will I append the parameter.

*) On Debian/Ubuntu, you can always override Amavisd default settings in /etc/amavis/conf.d/50-user. Check our short comment here: http://www.iredmail.org/docs/file.locat … ml#amavisd

*) Check Amavisd official document to find examples of how to set '$banned_filename_re'.

Do I have to set any ldap attribute to that user so he is the only one affected by the banning of all attachments?

LDAP integration will be dropped in upcoming iRedMail-0.9.0, so, for per-user restriction, I suggest you enable policy lookup in Amavisd, then you can manage it in SQL table "amavisd.policy".

Reference:
- http://www.iredmail.org/docs/amavisd.pe … ookup.html
- http://www200.pair.com/mecham/spam/bypassing.html#8

By the way, upcoming iRedAdmin-Pro release supports manage per-recipient policy, although Amavisd supports query per-recipient 'banned_rulenames' from policy table, but iRedAdmin-Pro doesn't manage its value yet. Will try to improve it in iRedAdmin-Pro in the future.
