How PageGate Sends Email Transcript for Video:
Welcome to the video tutorial on how PageGate sends email.
SMTP is the protocol used to send email of all varieties, including those delivered as SMS; nearly every US and Canadian carrier supports text messaging to their phones using a public access SMTP/Email gateway.
PageGate has an email server engine as a core part of the program and this gives you the ability to send SMTP/Email messages in one of two ways: Direct and Relayed
To explain the difference between the two, direct delivery allows PageGate to function as a mail server to deliver email/SMTP messages on behalf of your domain.
Relayed delivery configures PageGate to pass all of its traffic through a verified SMTP server for delivery, like an email client.
Technically, direct delivery is more efficient and reliable because it removes at least one hop in the delivery sequence and also means that PageGate isn't reliant on another mail server for delivery. However, when you have PageGate use direct delivery for SMTP/Email, it will function as an email server and attempt to deliver traffic on behalf of the configured email domain. This means that you'll need to abide by all of the rules required of a mail server because, again, the program will delivering SMTP/Email on behalf of your domain. This is incredibly important to note because, in an effort to combat spam, most US and Canadian carriers pay respect to SPF records.
SPF stands for "Sender Policy Framework" and is a record of public IP addresses that are allowed to deliver email on behalf of your email domain. This record is published by whoever owns and operates the email domain. If the PageGate server's public IP address is not part of your email domain's SPF record, your messages will may be filtered as potential spam for failing the SPF validation check. If you continue to send traffic that fails SPF validation checks, the receiving servers will eventually blacklist your site from sending traffic to them.
Alternatively, you can use relayed SMTP delivery.
With relayed delivery, you're configuring PageGate like you would any other email client and telling it to relay its SMTP traffic through the specified email/SMTP server. Due to some of the complications involved in configuring the program for direct delivery and using it as a mail server, it's usually more practical to configure PageGate to relay its SMTP/Email traffic through your company or ISP's SMTP/Email server. However, doing so makes PageGate reliant on that mail server for message delivery.
This concludes the video tutorial on how PageGate sends email. For more information, including how to configure PageGate for direct or relayed SMTP/Email delivery.
