Topic: Checking email from internet takes ages

[Mark Thomas]

Hi,

I posted this topic a while back and had a few good answers, (thanks!) but
unfortunatley none of them worked.

I have worked out that e-smith takes ages to reverse dns lookup  my companies firewalls external IP address - it doesnt have a DNS entry - just an IP.

Where could i put this ip, to speed up the connction process, as at the moment it can take upto 1 minute to connect. (I.e. would putting it in the /etc/hosts file help? I dont think so, but hey!)

And how could i turn off reverse dns lookups?

If you update your /etc/resolv.conf you could prevent DNS lookups from taking ages.  The synax is:

search
nameserver

This would speed up your DNS lookups because the E-Smith server wouldn't have to broadcast DNS requests.

The problem isn't with reverse lookup of the dns entry it is with the ident lookup.  Take a look at /etc/xinetd.conf.  There are some option at the top and some other under imap and pop-3

Ok thanks Shad,

I have had a look at this file - but i am not really sure what I should be looking at!

What options do i need to change?

Thanks

Take the USERID items out of the log_on_success and log_on_failure entries at the top of xinetd.conf.   Of course you have to do this in a templates-custom file to make the change stay.  You probably have a firewall dropping the ident replies from machines that send them and/or the icmp replies from machines that don't so you end up waiting for a timeout trying to get the userid.

Cool!

This works - thanks for the great replies one and all!
