In the past week I have received this error message several times when trying to send an email with T-bird 91.7.0. Most emails are sent but every once in a while they won't go. I can't figure why. Any ideas? Something to do with the content?

Sending of the message failed. The message could not be sent using Outgoing server (SMTP) mail.tds.net for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Sorry... I should have given more details. My ISP's SMTP settings are correct. I can send several emails with no problem and then this message pops up on the next email. Then I can send several email again with no problem. It's very erratic. I'm wondering if it has something to do with the content of the email... for example when I'm forwarding a certain web site.

I suggest you log your sending of mails so there is something to go on when it fails.
