Hello, Gmail is blocking my emails that I send to Gmail. I have a personal email account with StackCP. The info says I need to set up an SPF record on my server. I found where to add it but don't know how to write the record. Here is the Google link with options for me: https://support.google.com/a/answer/1068...re-senders I'm using the first one in the list - "v=spf1 ip4:192.168.0.0/16 include:_spf.google.com ~all". If I use the third one, my TXT says "v=spf1 a:mail.stackmail.com ip4:185.151.30.158 include:_spf.google.com ~all". I don't know if the DKIM settings are right. I'm looking for help. Dan

Usually, an SPF record looks like this: Type: TXT Host/Name: yourdomain.com Value: v=spf1 ip4:[your ip address] -all Sometimes your IP gets blocked too. You might need to see if that IP is listed on a black list.

Here is a rewritten version of the text using simpler, everyday words:

FYI the IP address inside "SPF" (sender permitted from) needs to be the public internet address that people see online, not your private 192.168.x.x network number. If you can visit whatismyip.com from your email server, that will show you the right one.
