SMTP problem in Thunderbird

  coinneach 19:31 03 Feb 2008

When I try to send emails in Thunderbird, I'm told "Sending of message failed. An error occurred sending mail: unable to connect to SMTP server The server may be down or incorrectly configured. Please verify that your Mail/News account settings are correct and try again."
I've been through this and other rituals with BT with no satisfactory result. I noted that a moderator on the Thunderbird forum concluded some time ago that the problem was probably due to Norton. This doesn't apply in my case because I have the same problem on 2 networked computers and only one of them uses Norton!
Can anyone who has a fix for this tiresome glitch please let me in on the secret. (Fortunately Yahoo Mail is unaffected by this, so I'm not in purdah yet!) coinneach

Server name is probably, drop the smtp. bit

By email from coinneach:

"Hello Octal Thanks for your suggestion but I'm afraid I've been there several times without success. coinneach"

If you would mind posting replies in the forum please so that everyone can help you, because I'm not sure what else to try, thanks.

Just to confirm that the two suggestions so far have been to modify the SMTP address by dropping the smtp bit. This has failed to solve the problem.
There is something strange going on, because in the past I have always been successful in using - with or without my username preceding it.

Can you setup your SMTP in Outlook Express then try sending, if it goes import settings into Thunderbird

ping statistics: sent 4 received 4 lost=0 (0% loss)
approx. round trip in milliseconds:
min=58ms max=93ms average 78ms. (TTL was 49)

does this tell us anything, brundle?

I've tried Outlook Express, woodchip, but this won't work properly, either!
