[kwlug-disc] msmtp email to gmail not landing - ideas?

[B. S.]

I first tried mail.kwlug.org, got cert errors, changed to cpanel2, and 
that part got happy. (Authenticating via mail.kwlug.org id.)

Yes, it's coming from the VPS.

Curious it's only gmail unhappy.

I can't say I know what it should be set to - mail.kwlug.org / drupal 
can't be impacted by this. These are all @kwlug.org (outgoing) 
addresses. There is no and never will be a mail server here - outgoing / 
notifications only.

AFAIK, there can only be one reverse IP to name mapping. So it's not 
clear to me what to suggest. (It will never be able to get back, and I 
can't know what e-mail addresses might be used by other parts of the 
server later.

Help me understand ... Linux boxes all over the world have (internal) 
mail baked in - even internal notifications work that way. It's only a 
small step from that to sending the notification externally, and @gmail 
has to be a frequent destination. Especially with dynamic ip addresses - 
everybody can't set their reverse ip! Huh? (Grumble, at gmail, not you.)

[Let alone direct send to cpanel2 from Thunderbird identity just worked. 
Which wasn't from the vps.]
