Using an External Mail Server

PRO Server uses its own internal mail server to send out email alerts and reports. You can also configure PRO Server to use an external mail server.

1. Login into PRO Server admin console.
2. Select Settings > Server > Mail.
3. Under Mail Agent > Email Host, choose External.
4. Append a colon and the port to the hostname to specify the port: mail.acme.com:25
5. (optional) Specify a username and password if your mail server requires it.

SSL: true
host: smtp.gmail.com:465
username: <yourGmailAccount>@gmail.com
password: <yourPassword>

NOTE: You must enter your full gmail address (including @gmail.com) and Gmail password. PRO Server stores it so it can send email after a restart, but it is only shared with Gmail.

Either you are probably not connected to the Internet or the CrashPlan mail server is temporarily down.

• Make sure you can ping an external source like google.com from the command line: ping google.com

This occurs because PRO Server cannot figure out the hostname it is running on. You'll need to modify the startup parameters for your operating system and add:

-Dmail.smtp.localhost=localhost

(Or your server hostname). Email us for help with modifying the startup parameters for your OS.

If you think the external mail server is rejecting your connection and you have access to the mail servers logs, they may provide further information on why it's not accepting the connection.

1. Open a terminal window, then ping the mail server: ping smtp.acme.com
2. If that works, try telnet-ing to the mail server: telnet smtp.acme.com 25
   If that doesn't work, you may have a network or security issue external to CrashPlan

• If it does work, you can manually attempt to send a test mail to noreply@crashplan.com (which is what the PRO Server server does before it saves your settings).
