Hi All Having a problem with INTERNAL mail here and I was wondering if anyone could shed some light onto the problem.
Having just upgraded our 2 linux proxy servers from RHL7.3 to RHL9 it has just become apparent that internal mail (clients using Outlook) are taking upto 3 minutes to connect to our mail server (Solaris 9 - running sendmail). Our two proxy servers are configured in the following way Proxy 1 Public IP = Internal 1 = 192.168.1.1 Internal 2 = 192.168.4.1 Proxy 2 Public IP = Internal Card 1 = 192.168.2.1 Internal Card 2 = 192.168.3.1 Both running Red Hat Linux 9, Squid Dansguardian sendmail (for the admin accounts on the machine - no clients) bind-9.2.1(Caching Only Nameserver) With our mail server (mailhost.bsfc.ac.uk) having 4 internal IP numbers in addition to its public IP address. 192.168.1.252 192.168.2.252 192.168.3.252 192.168.4.252 If I give a workstatino a public IP address and bypass our proxy server(s) I connect almost instantaneous, the same goes for any internal user who uses our WebBased E-Mail (horde) which is located on our mail server (external). Which leads me to believe the problem lies with squid/dns/sendmail on the proxy servers. Our mail server does not have any problems with IMAP or POP3 and works perfectly. I tested this by putting in a dummy server running RHL7.3 in place of our main mail server to eliminate our mail server - no change. Could it be an internal DNS isssue, we don't actually have our own DNS server here (the two proxys are configured to use caching-only), and are set to look at our main DNS (hosted by www.ja.net). I will be putting in our own DNS once I get time.
