Re: Something very wrong with my spf record/Me
[In reply to]

Hi,
I'm trying to figure out what it is you want to accomplish. You have an
email server on your host, and want to send email from it. I'm not sure
what this email has as a MAIL FROM:, so i'm not sure how to help you
here.
However, if there is an MAIL FROM present, the HELO is not important.
The SPF record from the domain in MAIL FROM is usually used to check the
IP of the sending MTA, unless MAIL FROM is empty (which happens when
mail is bounced for example) in which case HELO is used.
Also, when I do a TXT lookup for smtp.nildram.co.uk, there is no TXT
record in the response, so smtp.nildram.co.uk does not publish spf..
Kind regards,
Koen
