My OS in
Windows 7. I'm using
Thunderbird 3 from my home to access office mails. Though my office mail server doesn't support
POP3, Thunderbird automagically configures itself when I provide it my email id and password. It can download emails and synchronize with server. However, I get following error when try to send a message:
Sending of message failed. An error occurred sending mail: Unable to authenticate to SMTP server smtp.[omitted].com. It does not support authentication (SMTP-AUTH) but you have chosen to use authentication. Uncheck 'Use name and password' for that server or contact your service provider.
I didn't find anywhere from account settings dialog box a check box saying
Use name and password. I tried disabling secure authentication by unchecking the check box
Use secure authentication in
Server Settings dialog box but it didn't solve the problem.
Any idea how to get rid of this problem? Thanks for your time.
