The ‘all’ mechanism at the end of your SPF record, and use it with the ~ (softfail) or – (fail) prefix. When no prefix is set, the + (pass) is used by default. Mistake : The Use of the ptr Mechanism The SPF ‘ptr’ mechanism is used for reverse DNS lookup that returns the hostname to its corresponding IP address. This information is helpful to B B brands in particular. But this mechanism has reliability issues and causes a burden on the reverse DNS servers and email systems connected to them. That’s why RFC discourages the use of the ‘ptr’ mechanism. In the majority of cases, you can replace it with the ‘a’ mechanism.
Mistake The Use of mx Mechanism Use ‘mx’ with Chinese Student Phone Number List domain names and not mail server names. Stating mx:mailserver.sample.com is considered incorrect unless you actually require SPF validation to look up all the hosts accepting mail for the ‘mailserver.sample.com’ domain. In most cases, there won’t be any such hosts as ‘mailserver.sample.com’ is itself a host and not a domain. You won’t come across this as a syntax error, but it won’t simply match anything. The correct way for validating against the MX record for.
When you’ve to define a certain mail server’s hostname or IP address, should be used Mistake : Creating an SPF Record Without Proper Research This is especially for ISPs. Don’t create records with half information about the domain, its owner, and the brand it belongs to. Research what email server they use otherwise you might end up blocking their outgoing email delivery path from their in-office mail server. Mistake : Typos Avoid making common mistakes while configuring SPF settings by double-checking the SPF record for typos. You may type ‘inlcude’ instead of ‘include.
