Can I setup a Rogers account using GMX much as using Outlook Express?
Yes, you can set up a Rogers account. To do this, some settings need to be updated first. Access the Support forum and click the drop down menu listed on the page. Select Other email client not listed here and follow the instructions. You will have to configure the email client to use POP and SMTP to receive and send emails.
