I'm trying to setup sendmail for my mailserver as well as my PHP scripts and It isn't working at this point

My mail.log shows the error

Jul 22 15:18:54 WebServer sendmail[1365]: NOQUEUE: SYSERR(nobody): /etc/mail/submit.cf: line 417: readcf: option RunAsUser: uid value (-2) > UID_MAX (2147483647); ignored

everytime I execute mail() through PHP.

What is this and how do I fix it?

just off the top of my head it looks to me as if your sendmail is incorrectly configured.

from your posting it looks as of you sendmail is trying to start as the user nobody, which normally does not exist, so it will fail

try editing the file /etc/mail/submit.cf on line 417

what does it say?

if it says nobody, change it to sendmail, or something
then make sure the user exists on your system, to see if it exists try:

cat /etc/passwd | grep <userhere>

where <userhere> is the name of the user you put into the config file

if this command returns nothing ( just either, a blank line, or a fresh command prompt ) then your need to add a user in to the system

if the line 417 in /etc/mail/submit.cf says something different other than a username, past it back here and we'll have a look at it


hope this helps

Line 417 reads as follows,

# what user id do we assume for the majority of the processing?
O RunAsUser=smmsp

I tried cat /etc/passwd | grep <userhere>

and with user smmsp, I get

smmsp:*:25:25:Sendmail User:/private/etc/mail:/noshell

back. Please let me know what you think.

Where does that UID of -2 come from? Try changing that to the actual UID for nobody or whatever user your script runs as.

whats the easiest way to switch the UID in the situation ?
