Hi Joachim,

How are you sending this?  What is your email client and version?

We have in recent months updated our DNS records for GSuite to use DMARC and DKIM.
In fact there is a thread here about it because Google turned on some new stuff that was flagging our emails everytime we did a forum post

I'm using Thunderbird 60.6.1 (64-Bit) on a Mac with Mojave.

The mail included a few screenshots, but the error message doesn't really indicate my mail was flagged as spam or such...

I've communicated with Mariano using the same mailer and address just two or three days ago...
