Richard,
I too am using Windows 7 64 bit, and have been dealing with this issue for months now. I had to switch back to Outlook because I could never get Zimbra to reliably send my email.
I had issues with both Yahoo! mail accounts and a gmail account. What email service are you using?
Secondly, I never tried turning off the spell-checker as was suggested by Xarz991, but I'll try that since I'm out of ideas.
Normally, when I boot up my computer and try to send the mail, it works once. Then I have to close down Zimbra and restart my computer to send mail again. Have you experienced this?
Anyway, just wanted to hear if you found a solution. I did notice that there is a known issue with the Yahoo! mail server, from another post.
Good luck and let me know if you've uncovered any solutions!
