A simplest way is to add nagios user in exim group. (/etc/group file).

With this solution There is no need to modify check_mailq plugin and using sudo.

PS : On Debian , group is called Debian-exim

Thanks for the informative article.
I was stuck with this problem for weeks!

As per your suggestion I ran su command first (I added the shell option because by default nagiios account has no shell on Fedora 15)
su -s /bin/bash nagios -c “./check_mailq -w 5 -c 10″

When Linux complained that sudo requires a tty then I added the following entry to sudoers file:
Defaults:nagios !requiretty

Problem fixed! Thanks and keep up the good work.

I had a similar problem as Arun. In my case, it was because the utils.pm was pointing to a soft-link, rather than the executable. Changing MAILQ in utils.pm to directly point to /usr/bin/exim (I use Debian Lenny, and Exim4 is the MTA).
That got me around the above error, but now I get a /usr/bin/exim4 is not executable by (uid xxx:gid(xxx:xxx)) – the UID and GID for nagios.
Ugh. Thanks for pointing me in the right direction, though. I’ll let you know if I find a solution.
Cheers,
Matt
