Re: something like smtp-limiter plugin for ISPConfig

[Poliman - Serwis]

Thank you for answer. This plugin gives ability to limit number of sending
emails. Above some value user's account is blocked and mail is send to
administrator. I use postfix with ISP Config. It does not have to be plugin
for ISP. It can be something just for postfix which can be manage as shell
user in linux console. Of course if some plugin for ISP is, I would be
happy to know about.

What does that plugin do?  What is the actual problem you're trying 
to solve?

BTW, this is not the place for ISPConfig support.  If you're using 
Postfix through some kind of management frontend, you need to use 
support offerings of that company or their user community.

I'm going to guess that the real problem might be spam sent by 
authenticated users' malware.  You can mitigate that with content 
filtering on submission mail, specifically with URIBL lookups, 
because practically all of this malware will be spewing references to 
URIBL-listed web sites.

Also, a policy service such as postfwd[1] or cbpolicyd[2] can be 
deployed to limit users' sending.  Generally this kind of malware 
exceeds a human user's ability to send mail.

Hi people,
I am looking for some plugin which is similar to smtp-limiter which is for
DirectAdmin. It would be nice if there would be any. If not, is there any
similar plugin which can be manage by the linux console?
