Hi. I have spf record quesiton. My mail is hosted by zoho mail. I have no issues there. But I have an AS400/iSeries that I am sending out emails nightly to customers with shipping info. For example those emails are coming from S103jmr4.xxx.com (xxx being our domain name). The idea I believe is to add an spf record with that special name in it so that people will receive those emails, but I want to make sure that people keep receiving the normal mail. I used an spf builder to create a record using the S103jmr4.xxx.com. But does that spf need to include info about the zoho mail server too?
Here is the spf record created.
xxx.com. IN TXT "v=spf1 mx ptr a:s103jmr4.xxx.com ?all"
