Hi,

My thunderbird has seen fit to change its outgoing messages to 'plain text'. My ISP doesn't recogise this for some reason. How, please, can I change the messages to HTML?

Edit > Preferences > Composition > General > Send Options

I find it very odd that your mail provider would have a problem with plain text email. If you read the original IEEE standards, plain text was the ONLY supported format.

Make the change as described, but please return and let us know how it comes out.

I've got this wrong. I've used edit, preference, composition, general, send options, as instructed and I still can't send emails. So plain text isn't the problem. Sorry about that.

I thought plain text was involved because I used Kmail (as a check to Thunderbird) and one of the panels that came up seemed to mention plain text as being part of the problem.

So I'm left with my ISP not recognising my password when I send. I've used it for years. I've tried re-installing the account but that had no effect. If either of you can help with this I'd be grateful.

I now have Horde on my machine which is working well on both receipt and sending of emails. So I can now email my ISP for help. I'll probably switch to Horde altother in due course but I would like to be able to use Thunderbird to notify all my existing email contacts of the change.

Thanks for your replies.

So you can change sending setting in old format in thunderbird.

Narindersinh,

Yep, all sorted now. Thanks.

So, just to make things clear, the real problem was with your communication with the ISP mail server and not the mail format at all?

Did you get Thunderbird working with your ISP mail server, or work around the problem a different way?
