Can receive but can't send emails via Thunderbird.
I'm with BT and recently changed my password with them. Presumably as a direct result I can still receive emails through Thunderbird but can't send them (though both work fine if I use BT's own web service).
Initially I was getting 'timed out' responses but I've been running through some of the previously suggested fixes and am now at the point where I'm trying to enter the password (to login to BT server) and it's not being recognised.
All of the primary account settings seem okay, so I'm running out of ideas that aren't beyond my limited level! Any help would be greatly appreciated.
Many thanks,
