Connected to localhost.
Escape character is '^]'.

but from another machine i get

could not open a connection to host on port 143: connection refused

Are you running a firewall at all? Is the rest of your networking up and running? Which IMAP server you using?

cheers

hi jdharris,

i am using the uw imapd on rh8.0

The network is fine as i can telnet to all other ports ftp, smtp, telnet but not imap.

I have not every configured a firewall but then i did upgrade from rh7.1 to rh8.0. Maybe the upgrade installed a firewall i don't know about it? I checked for a process called 'ipchains' but nothing like that seems to be running.

Is there something obvious that i have missed?

thanks

To check for any filewall rules use iptables -L, as its done by the kernel you don't see anything in your process list. I'll have a look into how you would stop UW imapd from accepting connections from specific addresses.

thanks jamie,

I ran the iptables _l and i got some reply that indicates that my iptables failed due to missing ip_tables.o files. So i guess i don't have it running?

any ideas how/why IMAPD can be preventing taking connections from certain ip addresses?

thanks
