The email setup dialog is used to set up emailing for alerts. If you're not using alerts, or you're not interested in having the alert system email you, then setting this up is not required.
All outgoing emails will have a return address. To customize this address, enter a sender name and sender email address using the following format:
"Sender Name" <firstname.lastname@example.org>
Please make sure you specify a valid address here since this is where all the bounce messages will come from. Some ISP SMTP servers only allow emails sent out with a "from" address of their domain as well, so if you're having problems getting the SMTP server to work, make sure you're using a valid return address.
Include "alert" samples in text message
If this option is checked, any outgoing alert emails will include text showing the samples that failed the alert. As each alert email goes out, the past history is marked as being sent already so that you won't get duplicate data in reoccurring emails.
The SMTP server is the server that your outgoing mails will go through. This may have been given to you by your ISP or your mail administrator.
The default port for most SMTP servers is 25. If you connect to your SMTP server via a different port, then enter that port here. Leaving this blank will use port 25.
Some SMTP servers require a username and password to be able to deliver mail. If this is the case with your server, turn on the "Use SMTP Authentication" checkbox, and then enter your username and password. The password is saved in your MultiPing.ini file using a basic XOR encryption scheme - this will keep your password hidden, but this encryption method is relatively simple to "crack" if someone really wants to figure it out.
Use STARTTLS encryption if server supports it.
Most current SMTP servers prefer or demand the use of a secure channel to protect your username and password. If you use one of these servers (GMail is a great example of one), then you'll need to turn on STARTTLS. For more details on this topic, see our knowledge base article.
