Version:           kmail 1.9.6 (using KDE KDE 3.5.7)
Installed from:    Fedora RPMs

I'm using kmail 1.9.6 on Fedora 7 (x86_64) configured to check 14 POP3 accounts.

I'm intermittently receiving "Unknown host" errors when I attempt to check for mail on these servers.

Since a number of the accounts reside on the same physical server, and say 5 connections are working and one isn't, then the host is definitely present and responding correctly. Rechecking the mail again against all accounts then works correctly 90% of the time. Checking for a third time seems to work 95%+ of the time without generating errors.

Pinging the host proves that the server is indeed responding.

I believe that this is unexpected behavior, and that when I click the "Check Mail In" button email should be received from all accounts.

There is nothing in the remote mail server log (server is running courier) to indicate any failures.

Connecting from other mail clients on this PC (Evolution for example) works as expected without generating any errors.

Changing the connection preferences in kcontrol has no effect and the errors are still generated in kmail.
