Hello Friends,
I've exim 4.69 as my mailserver.
I have dns info like following
Code:
domain.com 10.10.10.1
mail.domain.com 10.10.10.2
a.domain.com 10.10.10.10
b.domain.com 10.10.10.11
c.domain.com 10.10.10.12
.
my system's hostname is
I've set these options
Code:
Send HELO based on the domain name in /etc/mailhelo
Send outgoing mail from the ip that matches the domain name in /etc/mailips
It works when I send a mail from
user@c.domain.com
then c.domain.com's ip is used.
But the problem is that if anyone does a helo to
any of my subdomain e.g b.domain.com
then It shows
Code:
Trying 10.10.10.11...
Connected to b.domain.com.
Escape character is '^]'.
220-mail.domain.com ESMTP Exim 4.69 #1 Thu, 03 Dec 2009 09:31:46 +0100
220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.
quit
221 mail.domain.com closing connection
Connection closed by foreign host.
This is a problem because no matter any subdomain you do a helo to,
you get mail.domain.com in response which is system's hostname.
What I want is if someone does a helo to for example a.domain.com then it should be shown
Quote:
|
220-a.domain.com ESMTP Exim 4.69 ...
|
not the system's hostname ...
Because now if you do helo to any of my subdomains or domains my mailserver shows system's hostname (mail.domain.com) as it's name.
In exim.conf if I set primary_hostname to for example xyz.domain.com then if you helo to any subdomains then my mailserver shows (xyz.domain.com) as it's name.
But I really want exim to dynamically show domain/subdomain which is being heloed.
e.g ... if I do "telnet c.domain.com 25"
then I should be shown
Code:
220 - c.domain.com ESMTP Exim 4.69 ...
quit
221 c.domain.com closing connection
Connection closed by foreign host.
and if I do "telnet b.domain.com 25"
then I should be shown
Code:
220 - b.domain.com ESMTP Exim 4.69 ...
quit
221 b.domain.com closing connection
Connection closed by foreign host.
The transport configuration in exim.conf if following
Code:
begin transports
remote_smtp:
driver = smtp
interface = ${if exists {/etc/mailips}{${lookup{$sender_address_domain}lsearch*{/etc/mailips}{$value}{}}}{}}
helo_data = ${if exists {/etc/mailhelo}{${lookup{$sender_address_domain}lsearch*{/etc/mailhelo}{$value}{$primary_hostname}}}{$primary_hostname}}
dk_remote_smtp:
driver = smtp
interface = ${if exists {/etc/mailips}{${lookup{$sender_address_domain}lsearch*{/etc/mailips}{$value}{}}}{}}
helo_data = ${if exists {/etc/mailhelo}{${lookup{$sender_address_domain}lsearch*{/etc/mailhelo}{$value}{$primary_hostname}}}{$primary_hostname}}
dk_private_key = "/var/cpanel/domain_keys/private/${dk_domain}"
dk_canon = nofws
dk_selector = default
I hope you've got the picture and looking forward to your help.
Thanks
exim - helo_data and primary_hostname for different subdomains with different IPs
