Domain literals, email not delivered, frozen

[gpilot]

Greetings all:

Can anyone help with this? Am running Centos 4.7, Cpanel 11.24.4, Exim v4 with Chirpy's csf and lfd installed.

We are going to migrate to a new server. After transferring all the accounts to the new server, but before changing the DNS entries which point to the old server, I would like to send emails to users on the new server in the format "userid"@[206.XXX.XXX.XXX] where 206.XXX.XXX.XXX is an IP on the _new_ server. This is the "domain literal" format.

Without changes to exim.conf, the emails are rejected "domain literals not allowed" in the message from the server at SMTP time.

I tried modifying exim.conf by uncommenting "local_domains_include_host_literals" as sugested in the file:

# If you want to accept mail addressed to your host's literal IP address, for
# example, mail addressed to "user@[111.111.111.111]", then uncomment the
# following line, or supply the literal domain(s) as part of "local_domains"
# above.

local_domains_include_host_literals

but upon restarting Exim I would get a "Exim configuration error" and the service would not start.

Chirpy's suggestion is adding the line:
"allow_domain_literals" to the first open textbox in Cpanel advanced conf. editor. He also suggested adding the IP used in the address field to the etc/localdomains file in the format [xxx.xxx.xxx.xxx], brackets included.

The result is that there are no more bounce messages, however the emails are not being delivered. Each account on the server has a dedicated IP. The exim maillog indicates the email is "frozen".

This happens whether I use an external email acct to send or if I send from the same account on the server.

There was another post somewhere which suggested adding the "@[] as a line in etc/localdomains however this does not seem to change anything. I have also tried adding the IP in the address to the etc/localdomains (within [] without success.

Exim v3 did not have this problem.

Help!! Thanks!
