We have 6 RHEL4 Linux servers in the company. Some users use Mail program to send emails.
srv1, srv2 and srv3 can send email normally.
srv4, srv5 and srv6 no.
So.. I was searching for an How To document, in order to check all the configurations on the various servers for the program Mail.
The only file I checked is mail.rc, and it's the same on all 6 servers.
Moreover.. when I try to send mails from the srv4, I receive the following error message:
WARNING: RunAsUser for MSP ignored, check group ids (egid=611, want=51)
can not chdir(/var/spool/clientmqueue/): Permission denied
Program mode requires special privileges, e.g., root or TrustedUser.
Any help is welcome. Thank You!!
