Hello,
Thank you for contacting us about issues accessing webmail. This was a known issue on your server, that our System Administrators were working to correct. It is now working again correctly. Also,you can always access with the "webmail." option.
For example:
webmail.example.com (Be sure to replace example.com with your actual domain name).
Since this is just our public forum, I marked out your domain name for security purposes.
Let us know if you have any further questions.
Thank you,
John-Paul
