SubjectPOP3 Error
Hi Folks,

I got a problem with POP3.

I'm running Kernel 2.0.15 and since I made a boot all users who
are accessing their Mail Boxes they got the following message (Netscape):

"An error occured with POP3 Server, please contact the administrator
of this system or try later"

I guess it's not a passwd error (I made some changes deleting
passwd.old, passwd.OLD and passwd~) since I got the netscape error I undid
that by copying the current passwd to passwd.old and passwd.OLD
I also guess it could be due a boot (I've compiled the kernel
2.0.15 but I might have not updated some files). Well. I hope you could
help me. Here is some usefull information:

cpu:/bin# ls pop3d -l
-rwxr-xr-x 1 root root 34933 Sep 1 23:12 pop3d*

# If you make changes to this file, either reboot your machine or send the

# "kill -HUP <pid of inetd>".
# The inetd will re-read this file whenever it gets that signal.
