.oO(oh my god... I just told that postfix has not that feature requested by [email protected]. For this _something_ like http://www.policyd.org/ is needed. I pray that sometime people will stop "answering" not asked questions)

Hi,
I'm using RC .0.8.4, MTA is Postfix (on Centos 6).
There is a way to limit number of messages that a particular user can send at
one time?
For example: not more than 10 recipient for single message or not more that 50
message/hour?

this is a POSTFIX question not roundcube
imho it is not a postfix question, postfix is not ready for this...

ah rate control from webmail per user
no way without heavy logging - no thanks not for me

anvil_rate_time_unit               = 1800s
smtpd_client_connection_rate_limit = 50

50 messages per half an hour and IP

...as you said: per IP.

yes, as you are do the same on httpd-side to block bots
but not on the application layer -> iptables-ratecontrols

If the IP is that of your webmailer... one user causes the whole side to be 
throtteled... (not that funny unless
every user has its own roundcube)

You need some more magic software (plugged to postfix or to roundcube) for 
this. Postfix can't help you out (for
Squirrelmail there are such addons)

not more than 10 recipient for single message

is clearly a MTA thing

smtpd_recipient_limit = 10 and you can have a own smtpd-process
configured in master.cf to not fuckup regulary users
