Hi there,

This is my first time posting here, and I'm not sure if it's the
right place or not to ask my question. This is a general DNS
question, specifically, I think, SPF.
Probably not really the right place but the SPF users' list has been a
bit dead for a while so let's see what happens.
I host email using SmarterMail, and all 400+ customers either use a
regular email client (desktop app/mobile device) or the webmail interface.
One particular customer wants to use Gmail as their email client for
sending email from their domain.
What's the domain?
I helped set up the settings at gmail for the SMTP server, and did
the google-siteverification and added _include:gmail.com_ to the SPF
TXT record,
The gmail.com SPF record is just a redirect - wasteful. I'd suggest
include:_spf.google.com
instead.
as well as DKIM and DMARC configured. I get green lights for the
domain from Dmarcian (well, they said I had a duplicate SPF value,
which I have removed).
The emails that get sent *do* arrive for other users on my email server,
but *not* to email addresses off-server, ie; @live.com
I can see the traffic from gmail in my logs, and it appears the emails
are sent, but they do not arrive.
Stumped. Any spare brain cells available out there would be appreciated.
Can you show us a log of one of the transactions? Or perhaps get the
customer to try to send mail to me, I should be able to see everything
that's needed in our server logs.
