Gmail was OK at the beginning, but at some point began to send emails
from my server to spam. I asked google twice and got no answer. I read
and reread their recommendations many times. Till now I do not know why
they do it. Probably they do not want people self hosting and make
their servers unusable.
I've also hosted my personal mail server for many years and I started
noticing that all mails would start going to spam on Gmail recipients. I
eventually changed to a new IP and they started working again. The old
IP got blacklisted at some point, and while it got whitelisted, its
reputation with Gmail probably never recovered.
That said, they still go to spam occasionally with the new clean IP and
I have a hard time understanding why. I like mail servers (probably in a
minority here) so it's frustrating that I get stopped by external
factors, since it seems to be passing rDNS, DKIM and SPF checks.
I have noticed that when I send some log files from my servers to gmail,
they get flagged as spam. I guess that they think that a server with no
regular users is not considered to be a legitimate source of mail.
I have often wondered why so few e-mail servers use IPv6. From what I have
read, gmail is one of the few that can use IPv6, but if you send e-mail to
gmail using IPv6, the messages are treated as spam. I readily admit that I
have not tested this myself, yet.
It could be worse, though. I don't thnk that many people realize that you
can sometimes send e-mail to SMS messages on your cell phone. For verizon,
you just send it to the telephone number @vtext.com or @vzwpix.com. For
example, if you telephone number as (123) 456-7890 with Verizon, you would
send it to [email protected]. It is limited to 140 characters. The big
problem was that after something like 4 or 5 messages, it would filter
them out. That makes gmail look much better in comparison.
