Hello,
I recently upgraded my mail server OS (Debian 7 to Debian 9), and at the
same time got
the latest postfix package for Debian 9.
It is hosted in the cloud (Linode), and I completely rebuilt the
instance, rather than
doing an upgrade. The IP addresses (v4 and v6) are the same. The config
didn't
change (I use ansible to deploy both the software and config - no manual
steps required).
After the upgrade, I sent a test e-mail to my gmail account, and it went
to the
Junk folder. I moved it to my regular folder, and after that e-mail to
my gmail
account was delivered normally.
My wife sends e-mail to the Washington Post (perhaps hosted by Google as
well)
and they are not receiving her e-mails. They are delivered to the mail
server, so I
strongly suspect they are going to junk as well.
Is there any reason the software upgrade would cause this behavior?
I can't think of one, but the timing is very coincidental.
Thank you
John
