Due to the Heartbleed bug we have had to update all of our own SSLs including on our shared mail servers. We are seeing Mac users reporting they are getting errors such as “Invalid Certificate Error” or “Invalid SSL” when trying to send mail.
If you are seeing this error please do the following and you should then be able to send mail as expected:
- Go to Applications
- In the utilities folder click on the icon for keychain access
- In this application find the mail server that you are using and right click and click “delete”
This should then allow you to connect to the mail server correctly.
