How to change mail server ip address in PLESK

How to change mail server ip address in PLESK ?
Ans :
If primary mail server ip address is  blocked in any spam checker sites ( eg BARRACUDA,SORBS-SPAM etc)  then there is only one solution, that is change the mail server ip address on the server.
You can easily change the mail server ip address in cpanel by using /etc/mailips file. The same as in PLESK you can also change the outgoing mail server ip address by using “/var/qmail/control/smtproutes” file.
1) first check the domain name which is hosted on the server by using following file
cat /var/qmail/control/rcpthosts
domain1.com
domain2.com
domain3.com
domain4.com
domain5.com
2) By default the “/var/qmail/control/smtproutes” file  is not present on PLESK server, you need to create it.
vi /var/qmail/control/smtproutes
3) Then add the new ip address in the following format.
domain1.com:192.168.0.2
domain2.com:192.168.0.2

4) Save the file and restart qmail
/etc/init.d/qmail restart
Note: Please replace the “192.168.0.2” to original ip address and the “domain.com” equal the original domain name

    Hi…
    I’ve tried your solution but still not working…
    I’ve created that file and wrote in it:
    domain.it: xxx.xxx.xxx.232
    When I send mail to gmail rcpt, I got a “failure” message saying that xxx.xxx.xxx.231 is blacklisted
    Any other suggestion?

    1. Hello,
      I think your mail server ip xxx.xxx.xxx.231 is blacklisted in spam domain list.
      You can check your ip by using the URL http://www.blacklistalert.org/ and http://www.mxtoolbox.com/blacklists.aspx
      If your ip blocked in any site then you need to unblock it.
