Error + auto-reply not working
 

My system seems to have lot of issues these last days. ISPManager version 4.3.15

1. First my auto-reply doesn't work at all. Support doesn't respond to my inquiry.
2. Second, plenty of these messages in my log.

Do you have any suggestion how to repair that ? Thank you very much.

Sincerely,

tech support assistance is required

I already sent my request for assistance. No news for three weeks now.

send me a pm with your username. i'll check what's the problem there

Set /usr/local/sbin/sendmail folder permissions to 4555, executing the command chmod 4555 /usr/local/sbin/sendmail

Ensure that the sendmail binary is suid root to get the local delivery of messages correct

Chmod is done, sendmail is suid root. But still not work. Have this message in log:

Aug 7 08:50:12 mail sendmail[20989]: m77CoCZ5020989: SYSERR(mailnull): savemail: cannot save rejected email anywhere

Thank you for your help.

you will have to contact the Support Team once again. And they will need to access your server.
