Hi, i just installed postfix on my company and is working fine, now the
company management has asked me to
implement a group security model that i dont know if i could do it in
postfix, it goes like this :
1. We want to have a group of persons that can send and receive emails
without restrictions
Add them to a sender whitelist, with appropriate restrictions on the client
IP (or set up SASL/TLS for "road warriors").
Make sure to put this whitelist access map in front of any BLACKLISTS you
use.
2. We want to have a group of persons that can send and receive emails but
they cannot send attachments ( based on extensions .exe, .pdf,.xls etc)
Probably best done with a policy server.
Policy servers don't see message content.
Oh drat. That's what I get for responding about $feature_not_used_here.
A content filter would do the job, but is potentially expensive.
