Howto: Set up (free) mail sending
-
Email alerts can be a critical component of a Mango setup. Here are three ways to configure email sending.
[size=18]Option 1 - Google's restricted SMTP[/size]
This is the simplest method and the most flexible, as long as you are sending to a gmail address.
Advantages: You don't need to set up any accounts, and you don't need to provide any authentication, works with dynamic IPs.
Disadvantages: You can only receive mail if you are a gmail or google apps user, and some ISPs block port 25 to prevent spam.To use, simply enter aspmx.l.google.com as the STMP server in Mango's settings, and select port 25.
Leave authorisation and TLS unchecked/blank.More info here: https://support.google.com/a/answer/176600?hl=en
[size=18]Option 2 - Google's open SMTP server[/size]
This is a better option if you have a gmail account yourself, but want to send to recipients who may not, or if your ISP blocks port 25.
Advantages: Can send to any recipient, don't have to use port 25, works with dynamic IPs.
Disadvantages: Requires entering your gmail/google apps details into the Mango systemTo use, enter the SMTP server as smtp.gmail.com, select port 587, enable TLS and Authorisation, and use your full gmail/google apps account username and password for authentication.

[size=18]**Option 3 - Sendgrid Email
**[/size]
This is the most time consuming to set up, but offers the most reliable delivery.You will need to sign up for a free account at sendgrid.com, which means entering some personal/company information.
The free account allows 400 emails per month, with a limit of 100 emails per SMTP connection (Mango should only make one connection per email event so unless you are sending to 200+ users this should be fine).Advantages: Can send to any recipient, don't have to use port 25, works with dynamic IPs.
Disadvantages: Have to sign up for (free) account, sending limits of 400 emails/monthTo use, first sign up at sendgrid.com, then once the account is established, enter smtp.sendgrid.com as the SMTP server, port 587, with TLS and Authorisation checked. Use your sendgrid account username and password.
