How to limit number of SMTP receptionists in postfix?


In order to do it you can define smtpd_recipient_limit value in /etc/postfix/ on the mail service node:

  1. Add required number of recipients in /etc/postfix/ configuration file. For example:

    smtpd_recipient_limit = 100
  2. Restart postfix:

    [root@server ~]# /etc/init.d/postfix restart
    Shutting down postfix:                                     [  OK  ]
    Starting postfix:                                          [  OK  ]

IMPORTANT NOTE: It is global parameter, which will affect all existing postfix users, so make sure that specified number of SMTP recipients is enough for mail users.
