Hi Friends,

I have one Domain, which is maintaining 3rd party, xyz.com, we are paying annual base rent for this domain...they have given us some place and ID to create....

I am trying to configure mail.xyz.com with outlook express, internet is coming by squid server (RHEL-5).

i have opened port no 25 & 110 in iptables (TCP & UDP),

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 25 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 110 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 25 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 110 -j ACCEPT

Note: If i am connecting Internet direct from switch (If there is no Squid Linux Server) then Outlook express is working fine with mail.xyz.com, but if i keep squid proxy then only getting problem with mail.xyz.com...

When i run outlook exp with squid then i am getting below error

"The host 'mail.xyz.com' could not be found. Please verify that you have entered the server name correctly. Account: 'mail.xyz.com', Server: 'mail.xyz.com', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 11004, Error Number: 0x800CCC0D"

This only happens when getting internet vai squid, or else there is no error....I have tried with 2-3 domains, getting same error....This mail server not located at office, this is on rent base taken...

Please help me what to do to solve this problem...

Squid is for http,https,ftp kind of proxy.
Squid is NOT for email proxy.

Please show me your outlook configuration.

Hi sandeepc04,

I think your are using M$ Window$.
I don't know any thing about Window$.

Window$ passing packet to INPUT chain of Linux server, insted of FORWARD chain.

In Window$ client configure only router settings.
And configure proxy only in browser.

And add FORWARD chain rules for emails.

I think it may work.
