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?
