Fastmail

Access under Firewall

Alternate usernames

You need to log in with your full FastMail.FM username, i.e username@your.domain. You must use the username you used to sign up your account, not any aliases or virtual aliases.

Because some software has difficulty with the @ symbol you can use any of these alternatives:

• username@your.domain
• username#your.domain
• username/your.domain
• username=your.domain
• Firewall access

FastMail.FM has a special proxy system whereby you can access each service (POP, IMAP, SMTP, etc) through any port number. The server names are:

• IMAP: imap.proxy.messagingengine.com
• IMAP/SSL: imaps.proxy.messagingengine.com
• IMAP (alt namespace): imapalt.proxy.messagingengine.com
• IMAP/SSL (alt namespace): imapalts.proxy.messagingengine.com
• POP: pop.proxy.messagingengine.com
• POP/SSL: pops.proxy.messagingengine.com
• SMTP: smtp.proxy.messagingengine.com
• SMTP/SSL: smtps.proxy.messagingengine.com
• LDAP: ldap.proxy.messagingengine.com
• LDAP/SSL: ldaps.proxy.messagingengine.com
• XMPP: chat.proxy.messagingengine.com
• XMPP/SSL: chats.proxy.messagingengine.com

If you use these server names, you can use any port to access these services. Commonly open ports are 80, 21, 25 and 443.
