-=== Q: What is the difference between secure mail access and the not secure one? ===+=== Q: What is the difference between the secure mail access and the none secure? ===
 A: The concept is similar to HTTP and HTTPS. The secure mail access is a process that establishes an encrypted connection between you and the server, so that no one else (or machine) can observe the content that you are transferring, including your password and email content. A: The concept is similar to HTTP and HTTPS.

-===== Q: Why does my mail client warn me "the secure certificate is invalid" or "cannot verify server identity"? =====+=== Q: Why does my mail client warn me "the secure certificate is invalid" or "cannot verify server identity"? ===
 A: That's because each secure certificate has to verify against the server name that you connect to. If you connect to mail.your-domain.com, your mail application will warn you as the certificate belongs to someone else like *.agnx.com. You can safely accept the certificate coming from agnx.com as it is AfterOffice Global Network Exchange domain. A: That's because each secure certificate has to verify against the server name that you connect to.

-=== Q: What is the deferent between SSL and STARTTLS? ===+=== Q: What is the difference between SSL and STARTTLS? ===
 A: SSL is easier to configure as it is usually associated with a dedicated port number - although you need to get the port number right as SSL will be assumed running at the port. You cannot connect to port 110 with SSL for example, as the port has been reserved for plain POP3 connection (the secure POP3 port is at 995). Where STARTTLS is more advance since it is usually supported at the original ports (110 for POP3, 143 for IMAP, 25 and 587 for STMP etc). Connection to these "standard ports" will have to go with STARTTLS as it is more like a hybrid connection that starts as plain, switching to SSL after the connection is established. AfterOffice offers both SSL and STARTTLS at related ports. A: SSL is easier to configure as it is usually associated with a dedicated port number - although you need to get the port number right as SSL will be assumed running at the port.
