Delivering Emails Overview
When it comes to email delivery, there are two basic methods of delivering emails. Either you configure LiquidFiles to uses an Email Relay Mail Server or not. If you don't configure an Email Relay Mail Server, LiquidFiles will deliver emails direct to the next mail server.
- Configure/troubleshoot Email Delivery when using an Email Relay Server.
- Configure/troubleshoot Email Delivery when using Direct Delivery.
To check if you've configured LiquidFiles to use Email Relay Deliver or Direct Delivery, please go to Admin → Configuration → Email. If you've added a Email Relay hostname or IP address in the Email Relay Host field, you're using Email Relay Deliver. If you haven't added a Email Relay hostname or IP address, LiquidFiles will use Direct Delivery.
Configuration Overview
Email Sender Address Policy
The Email Sender Address Policy determines what From address will be set when sending emails. The different configuration values are discussed in detail in the Email Sender Address documentation.
Email Sender Address
When sending emails from the system itself, things like password reset emails and various notification emails, this is the email address that will be used. To ensure maximum deliverability, please make sure that this is a valid email address. It's generally a good idea to use an IT support email or similar.
Bcc All
If you want the LiquidFiles system to send a blind copy of all emails sent to a specific email, you can add it here.
Email Delivery Security Level
When Sending Outgoing emails, what security level do you require. Please note that setting a too strict security level will likely make sure that the LiquidFiles system cannot send any emails.
The Default Setting is "May" — opportunistic TLS, or put plainly, use strong encryption when sending emails if you can (if the receiving mail server supports it), but don't encforce it.
LiquidFiles uses Postfix as it's underlying Mail Transfer Agent (MTA) that performs the actual sending, queuing, handlig or all emails being sent. For a detailed description of the different TLS Security Levels, please see the Postfix documentation for a complete description of the SMTP TLS Security Level and what the different levels mean.
Email Relay Server
When configured, all emails will be sent using the configured Email Relay Server.
The default TCP port for all SMTP is 25, if you need to specify a different port, you can append :port, like:
mailrelay.company.com:587
This setting will use the system mailrelay.company.com and TCP port 587 for all outgoing emails.
Please see the Email Relay guide for a more in-depth documentation and troubleshooting when using an email relay system or service.
Email Relay Username and Password
