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 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:

username@mail.uh.edu
Firstname.Lastname@mail.uh.edu

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 did not send, you will have to change your reply-to email address on Eudora for Mac to be your default mail.uh.edu address. Here is how to do it:

Eudora for Mac
- In Eudora, select the Special menu, and then select Settings.
- In the window that appears, click on the Getting Started icon in the left column.
- Under the Sending Mail section, type in your username@mail.uh.edu in the Email Address blank.
***NOTE: Even though Eudora says "You only need to fill this in if it's different from Username@MailServer," it is better to be safe and enter your username@mail.uh.edu anyway.
- After entering your default mail.uh.edu email address, click on the OK button to save your changes.
