Respectively. Modifiers like r,l, or o are applied to extract particular elements of the address or domain, and delimiters like – or . help separate different elements within the macro. Types of SPF Macros SPF macros are denoted by different single alphabets or characters that are enclosed by curly braces and prepended by a percent (%) sign, that refers to specific mechanisms within your SPF record. Here are the core macros.
The “s” Macro represents the sender’s email Job Function Email List address. Example- Mark domain.com. % l : It’s used to denote the local part of the sender. Example- Mark. % o : This highlights the sender’s domain. Example: domain.com. % d : Similar to “o”, this Macro represents the authoritative sending domain. In most cases it is the same as the sender’s domain however, it may differ in some cases. % i : It’s used to extract the IP address of the sender of the message, e.g. h : The hostname specified by the HELO or EHLO command.
Used during the SMTP connection when the message is being sent is referred to by the % h macro. There are many more Macros that can be specified in your record, however, we listed some common ones. How do SPF Macros Work? With SPF macros, domain owners can specify references to certain mechanisms within their SPF record, thereby replacing these mechanisms. by the receiving MTA, the references are then used to extract the mechanisms and expand.
