• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service.

  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

All email users are not able to send emails any where through webmail. They are getting following errors:

" There was an error sending your message: sendmail returned error code 111"

It was working fine and suddenly all users failed to send emails. Outlook is working. I have restarted the machine it worked once and after that even reboot does not help. Please advise ASAP.

Screen shot is also attached. Please help us ASAP.

I can see SWSOFT Parallels failed to fix. They worked well but unfortunately failed to diagnose the actual problem. Per my working I checked the /var/log/httpd/error_log and analyzed and found it large number of descriptors issue. I used the following commands:

[root@sml104 logs]# ulimit -n
1024
[root@sml104 logs]# ulimit -n 2048
[root@sml104 logs]# ulimit -n
2048
[root@sml104 logs]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
[root@sml104 logs]# ulimit -n
2048
[root@sml104 logs]#

Now I have fixed it. I just want to know how do I confirm these change will not revert back. The command I used to increase the size is a permanent solution or I need to change anything else?

Why this descriptors limit needs to be increased, please advise me on this?
 
Hi, i did what you explain, but it didn't work for me, some other solution for this?
