Did think to check the gmail spam folder just in case. No joy.<br>
<br>
I'm connecting to <a href="http://cpanel2.indieserve.net" rel="noreferrer" target="_blank">cpanel2.indieserve.net</a> and authenticating with user <a href="mailto:vps01@kwlug.org" target="_blank">vps01@kwlug.org</a>. (Not to gmail.) So, SMTP authentication is successful.<br>
<br>
(I don't see any way to set SMTPAUTH authentication as a specific type of authentication, but I don't think that's what you meant. man <a href="http://msmtp.sourceforge.net/doc/msmtp.html" rel="noreferrer" target="_blank">http://msmtp.sourceforge.net/d<wbr>oc/msmtp.html</a> if useful.)<br>
<br>
I took a quick google at reverse dns and gmail and can see it's a problem for the world.<br>
<br>
Paul - have you had any issues sending from @<a href="http://kwlug.org" rel="noreferrer" target="_blank">kwlug.org</a> addresses to @<a href="http://gmail.com" rel="noreferrer" target="_blank">gmail.com</a> addresses?<br>
<br>
I took a quick run by <a href="https://mxtoolbox.com" rel="noreferrer" target="_blank">https://mxtoolbox.com</a> on <a href="http://kwlug.org" rel="noreferrer" target="_blank">kwlug.org</a> - it's not entirely happy.<br>
<br>
I'm a little confused, though - I could put any ol' from address in. The SMTP server swallows it up and forwards it on. Just what is google reverse DNS'ing against?<span class=""><br>

Try creating an authenticated user account and using SMTPAUTH if you are<br>
not already when sending from the kwlug VPS. The reverse DNS doesn't<br>
matter as long as it matches to one of the forward A records.<br>
<br>
Also check the gmail spam folder. Sometimes Gmail junks my 'alert' type<br>
emails.<br>

I can't say I know what it should be set to - <a href="http://mail.kwlug.org" rel="noreferrer" target="_blank">mail.kwlug.org</a><br></span>
<<a href="http://mail.kwlug.org" rel="noreferrer" target="_blank">http://mail.kwlug.org</a>> / drupal can't be impacted by this. These<br>
are all @<a href="http://kwlug.org" rel="noreferrer" target="_blank">kwlug.org</a> <<a href="http://kwlug.org" rel="noreferrer" target="_blank">http://kwlug.org</a>> (outgoing) addresses. There is<span class=""><br>
no and never will be a mail server here - outgoing / notifications only.<br>
<br>
AFAIK, there can only be one reverse IP to name mapping. So it's not<br>
clear to me what to suggest. (It will never be able to get back, and<br>
I can't know what e-mail addresses might be used by other parts of<br>
the server later.<br>
<br>
-----<br>
<br>
Help me understand ... Linux boxes all over the world have<br>
(internal) mail baked in - even internal notifications work that<br>
way. It's only a small step from that to sending the notification<br>
externally, and @gmail has to be a frequent destination. Especially<br>
with dynamic ip addresses - everybody can't set their reverse ip!<br>
Huh? (Grumble, at gmail, not you.)<br>
<br>
[Let alone direct send to cpanel2 from Thunderbird identity just<br>
worked. Which wasn't from the vps.]<br>

So on a Debian Jessie machine, I'm trying to get system<br>

<br>
I understand that default installs auto install localhost mail<br>
