I recently attempted to send an email from my mail.uh.edu account and I get an error.  What setting(s) do I need to change on Mozilla Thunderbird so I can send my messages?

In the Spring 2011 semester, mail.uh.edu system administrators implemented a system change to improve overall system performance and security. Email validation is now required to send messages from mail.uh.edu email accounts.

Email validation means that your reply-to email address must be your default mail.uh.edu email address in your email client software settings. When using the http://mail.uh.edu/ webpage to compose and send email messages, you are not affected by this change.

Your default mail.uh.edu email address should be listed as one of the following:


If you have recently attempted to send a message from your mail.uh.edu account and received an error that says "5.7.0 You have no permission to send mail on behalf of this person" and the email does not send, you will have to change your reply-to email address on Mozilla Thunderbird to be your default mail.uh.edu address. Here is how to do it:

Mozilla Thunderbird for Mac or Windows
- Click on the Tools menu and select Account Settings.
- In the left column, select the entry for your mail.uh.edu account (username@mail.uh.edu)
- In the Default Identity section, make sure that the Email Address is your username@mail.uh.edu
- Click on the OK button in the bottom-right corner to save your changes.

For a quick tutorial, with screenshots, on changing your mail.uh.edu reply-to address on Mozilla Thunderbird for either Mac or Windows, consult the documents attached below.

If you have any additional questions about changing your mail.uh.edu reply-to address, email validation, or alternate email delivery options, please contact the UH IT Support Center (UITSC) at 713-743-1411, or via email at support@uh.edu .
