Email, updates, iptables Issues

I've a new install of cpanel that will not let me receive mail. I've searched the forums and net, tried every fix I could find except rolling back to php 4.3.3 or 4.3.11 and still no luck.

cpanel has been pretty unstable a couple times in past couple days too. It spits out errors about being unable to connect, fatal error, etc. But the mail has been consistently the problem.

I have a pretty standard install; php 4.4.1, WHM 10.8.0 cPanel 10.8.1-R113 Fedora i686 - WHM X v3.1.0, Apache/1.3.34 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 FrontPage/5.0.2.2635 mod_ssl/2.8.25 OpenSSL/0.9.7f PHP-CGI/0.1b

I'd also like to know what happens to iptables when cpanel is installed. Its supposed to be there but I can't find it and get errors when trying to set rules.

I've used cpanel many times in past setups but this is the worst experience I've had to date. It has not worked out of the box even when trying clean installs on new machines .... twice!

Sure could use some ideas or help. Thanks

 

This is the error message from mail sent to domains on server:

webmaster@net-integration.net R=virtual_sa_user T=virtual_sa_userdelivery:
Child process of virtual_sa_userdelivery transport
(running command "/usr/sbin/sendmail -bS") was terminated
by signal 11 (Segmentation fault)

Hardware has all checked fine.

 

ram checked and good. Did the exim and cpanel runs as described already. No success.
This has happened on two separate installs (rebuilt box and installed again)

Operating system Fedora (Linux)
Kernel version 2.6.15-1.1831_FC4
Machine Type i686
Apache version 1.3.34 (Unix)
PERL version 5.8.7
PHP version 4.4.1
MySQL version 4.0.25-standard
WHM 10.8.0 cPanel Build 10.8.1-RELEASE 113


I've checked mx records, rebuilt bind, tried any number of things I could find. It all comes back to exim IMO.

Any other thoughts on the issue from anyone is appreciated and in the meantime I'm going to open a ticket..

 

It seems this is cpanel's sendmail wrapper erroring out. This was pointed out to me by a tech at my provider who found this topic.

This I also found and tried previous but without success. So I started looking at DNS issues which was clearly off base. The tech ran it again a bit ago and it worked this time.

the solution:

rm -f /etc/eximmailtrap

... the binary runs from the command line now and the mail works.

 

FYI:

This did not work after all. Bind screwed up, exim had fits and even more server software errors occurred ultimitely leading to a completely unusable system. Nothing works now, updates and fix scripts fail, and most services will not stay running. Forced to rebuild again I think after 2 failures on clean installs its time to drop the control panel.
