題目: RE: [Exim] fails to re-bind to port 25 after a SigHUP
Since this is a common mistake, why not add a small patch to exim to check
its SUID permission when it loads up. I'm sure a message in the LOGS would
save a number of admin headaches :)

That's your problem. Exim should be SUID root

I have:

rwsr-xr-x   1 root     exim     1818624 Jan 18 12:50   exim


As root do as

chown root exim

and

chmod 1755 exim

in the exim/bin directory.
