TITLE:
Changing IP of "Outgoing mail mode" (Postfix) to a specific IP will result in Web IP changing also
PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:Plesk Onyx 17.5.3 Update #38
CentOS 6.9 64bit
PROBLEM DESCRIPTION:CentOS 6.9 64bit
Changing IP of "Outgoing mail mode" (Postfix) to a specific IP will result in Web IP changing also
STEPS TO REPRODUCE:1. Add a new IP
Tools & Settings > IP Addresses
2. Change IP of "Outgoing mail mode" to new IP
Tools & Settings > Mail Server Settings > Switch an option of "Outgoing mail mode" to "Send from the specified IP addresses" + select new IP (after submitted it will take some time to finish)
3. Go to "DNS Settings" page of any domain and you will see IP of A record of "domain.com" has changed to above IP. Pinging and nslookup will show that IP is really changed. However, this will not be a problem if I can access website as usual BUT all website will show Server Default Page/CentOS Apache2 Test Page and some site worst as inaccessible. It seems Apache/NGINX configuration does not changed.
I tried to remove newly added IP but Plesk says "Unable to remove an IP address: The IP address is already used for hosting" (But I select it to use with Outgoing Mail, didn't touch with Hosting Settings)
All above problems will solve after Switch an option of "Outgoing mail mode" back to "Send from domain IP addresses". (DNS reverts to original IP but website needed few hours for DNS Cache expiring. IP can be removed without error about Hosting.)
Tested it three times, same results.
ACTUAL RESULT:Tools & Settings > IP Addresses
