SPF Lookup verifies the sender's identity when an email is sent out. It checks for correct syntax and other issues, such as missing nameservers, invalid or missing IP addresses, and incorrect TXT records. What is EasyDMARC's SPF Record Checker and Lookup Tool?ĮasyDMARC’s SPF Checker lets you verify if an SPF record exists on a domain’s DNS and if it’s deployed correctly. Setting an SPF record allows you to specify which IP addresses are allowed to send emails on behalf of your domain, and any emails sent from an IP address not listed in the record will be flagged as suspicious. Most companies and individuals use SPF records to prevent spoofing and enhance email security and deliverability.Īnother reason for setting up an SPF record is to help prevent your domain from being used by spammers to send out fraudulent emails that appear to come from your domain. The SPF record protects a company's domain from spoofing while improving its sender reputation with MBPs (Mailbox Providers) such as Google, Microsoft, Verizon, etc. If SPF passes, the email under question is authenticated and delivered to the recipient's mailbox. This record lists all mail servers authorized to send emails on behalf of that domain. SPF authentication works by setting a special DNS record for a domain. When an email is sent, the receiving server checks the sender’s return-path address and verifies if the domain in use has a valid SPF record. Depending on the qualifiers used (~, +, -, ?), this mechanism indicates how the recipient should treat emails from non-authorized sources. It should be placed at the end of the SPF record. Listing all your sending sources under this tag lets the recipient know that you verify all the added domains/subdomains as legitimate sources.Īll is a required tag. The include tag is of top importance for a correct SPF record. The exists tag checks whether an A record exists or not on the mentioned domain. It's a "not recommended" tag as per RFC 7208, because it spends too many DNS lookups. The PTR tag prompts a PTR check for client IP hostname(s). If left unspecified, it takes the value of the current domain. The MX record tag checks the MX record of the mail server(s). The A record tag allows the SPF to validate the sender by the domain name's IP address. This tag should include all the IPv6 addresses that are allowed to send emails on behalf of the domain. This tag should include all the IPv4 addresses that are allowed to send emails on behalf of the domain. If it's incorrect or the tag is missing, the SPF record will be ignored. See Zoho Creator fields to know which Zoho Creator field types are of time data type.The version tag. See date time functions to find the built-in functions applicable to time data type.Operations (like addHour, subMinutes) on TIME values which result in a value outside the 24-hour range will also result in an error.A value declared like " 23:59:60" would throw an error. TIME values in no way should fall outside the 24 hour range.It should be declared as " 00:15:12" and " 10 seconds" should be declared like " 00:00:10". Declaring this value as " 15:12" would be read as " 15:12:00". Care should be exercised while declaring a value like " 15 minutes and 12 seconds". For example, " 10 AM" assigned to a TIME field will be treated as ' 10:00:00 AM' and " 18:15" will be treated as " 18:15:00". However time values without the seconds ( hh:mm or HH:mm) or without the minutes and seconds ( hh or HH) part assigned to TIME fields will be accepted by defaulting the missing components.In the event the value does not conform to the supported time formats, an error message will be thrown. Declared time values cannot skip either the seconds part or seconds and minutes parts altogether.
