Email throttling per user or per domain? Say, allow 100 emails per hour.  Receive an email notice if such limits are reached. Or is this supported on the current version?

cPanel has a featured called "SMTP restrictions".  It would be awesome to have with CWP.

Thank you.

How about an option to kill all emails produced from a given domain. I have 8 websites on my server but only ever send email outside the server from one domain. Just a bit extra spam protection that might save your server being banned.

Please add support for sending email with multiple ip or IP for Domain, because i have 3/4 website with dedicated ip but email always sended from ip of server and not ip of domain.

I think You should remove all issue first and then make new functions.
for example in centos 7 there is a problem with this:
http://forum.centos-webpanel.com/postfix/i-can-send-emails-but-i-do-not-get/

Is there a plan to fix it by CWP becouse I do not know to fix it by myself or wait for your official fix.

I would like to have:
- option to setup other port for SMTP
- spam rate filter in dovecot that prevent spam via php mail function
- and of course all things mentioned earlier by other users

If You are still looking for developers - I would be intrested to work with You.
I have growing hosting company that choised CWP for admin panel due to use PHP in it.

This issue has been around for several months now for CWP7 users:

http://forum.centos-webpanel.com/spf/policyd-spf-skip_addresses-not-ip-network/msg14109/?topicseen#msg14109

Why hasn´t it been fixed permanently?

Try fixing such open bugs sooner - you intoduced the bug almost 3 months ago.......

The Data Center that provides my dedicated servers provides up to 256 IP addresses per server,
which means I could have up to 256 domains/sites each with their own dedicated IP address.
In Cpanel/WHM I can just select a radio button for On beside a line
Send mail from the account’s IP address
in the Exim Configuration Manager, and it also reliably creates a record so that a helo name which
equals that domain name is added to the code in each outgoing email.

It would be really great to have a similar feature in Postfix.

Currently I use the procedure shown at https://www.kutukupret.com/2010/01/02/postfix-bind-sender-domain-to-dedicated-outgoing-ip-address/
which works very well, but as its a manual procedure, its time consuming when there are large numbers of domains and IP addresses in each server.

Currently I have several IP addresses in 1 server, and around 6 hosting accounts on each of those shared IP addresses.
It appears that when emails are sent no helo name is included in the code in the email.
Could Postfix please be configured so that a helo name is always included in each outgoing email which equals either the sender's domain name or the name which equals the reverse dns name of the IP address that email is sent from.

Could Postfix please be configured so that for example a server with 20 IP addresses which had 10 hosting accounts setup on each of those 20 IP addresses would send mail using each of those 20 IP addresses as the sending IP address and as above reliably include a helo name in each email 
which equals either each sender's domain name or the name which equals the reverse dns name of the IP address that email is sent from.
