How to limit number of SMTP receptionists in postfix?
In order to do it you can define
smtpd_recipient_limit value in
/etc/postfix/main.cf on the mail service node:
Add required number of recipients in
/etc/postfix/main.cfconfiguration file. For example:
smtpd_recipient_limit = 100
[root@server ~]# /etc/init.d/postfix restart Shutting down postfix: [ OK ] Starting postfix: [ OK ]
