slow pop3 connection time out
i installed Mandrake LE 10.2. Works great... but at some users who using outlook it takes long to retrieve/send there email. Also when i telnet to that server the response (welcome message) is displayed after a few minutes ?
how can i resolve this, or is this a local DNS problem. btw. i don't user ispconfig cause this is only an email server.
Is your server in a local network, or is it directly connected to the internet? If it's in a local network, from where do your users connect? From outside the local network or from inside? Do they use the server's IP address or a host-/domain name?
What's the host name of your server? Does it resolve in DNS?
whoa... a lot of questions ....
server is local (10.10.10.15) via a FW connected to the internet. Users connection from internal LAN. pop & smtp server in MS Outlook (express) is server ip-address (10.10.10.15) hostname is mail.dltmedia.nl. only the hostname (mail) replys on ping.
at this moment de mx points to another ip-address (provider) but we want to receive out e-mail on this new e-mail server.
Another thing is that some mail domains arent resolved. Getting undelivered msg see below
This is the Postfix program at host mail.dltmedia.nl.

but when i send an email from my other account (isp) then there's is no problem.
This seems to be a firewall and/or DNS problem. Have you tried some other nameservers in /etc/resolv.conf?
could it be local dns, for instance that the pc which is trying to connect cannot be resolved by the e-mail server ? cause when i ping the pc by its netbios name it cannot resolved, but when i ping on the ip-address it reply's.
i also add the wins server in samba with the ip address from the win2k wins/dnc/dhcp server.
What's in /etc/resolv.conf?
