Why does ScanDBX only test POP3 and SMTP email servers?

Each type of email server (POP3, IMAP, HTTP, SMTP) uses a completely different method of communication with Outlook Express. Most Outlook Express users are using POP3 accounts for their incoming mail and SMTP accounts for their outgoing mail, so we focused on supporting these two server types first. Future releases of ScanDBX will add more types of email servers until all email server types are supported.
