I do something similar, but when I send an email to a person for the first time, it always ends up in the spam folder by GMail.
Taken from my smtpd.conf:
table secrets { mylogin = [email]@ziggo.nl:[pass] }
accept tagged DKIM for any relay via tls+auth://mylogin@smtp.ziggo.nl:587 auth <secrets>It kind of defeats the purpose, since now the third-party will be able to read all my outgoing emails, and have control over them.
Relaying via the ISP's mail server though (even with TLS) seems like it would disclose the message contents.
By the way, give a look at mail-in-a-box, another cool project that implements a ready to use mail server with great functionalities.
I'm surprised how easy it is, and having fun with sieve scripts :)
Good luck with your endeavour, it is if nothing else a learning experience. But it's important to keep in mind that if email is a critical tool for you (it is for many people, ymmv), toying with it may not be the best idea.
So, without any means to control it myself I'm now in the mercy of fastmail support unless I set up my own postfix/dovecot in the meantime. I guess it goes both ways.
I get the best of both worlds; I don't have to worry about being blocked when I send things, and if I ever have issue with gmail, I can stop using them without losing my email address.
But, that's a guess, and I obviously can speak on GPs behalf.
Also, you should be using your own domain with Gmail (or any other provider) so you aren't tied to anyone, anyway.
Extraordinary claims require extraordinary evidence. Please provide just a single reference to this claim.
Or whatever. I remember the feeling, not the mistake that caused it.
Once that single server goes down it’s suddenly the biggest issue currently keeping us from doing anything. Whether it’s because of something I did or an upstream outage doesn’t matter, I’ve still got to troubleshoot it and try to work around it.
For $5/m you could have FastMail do it for you, or for free you could have Google do it. Yes there are trade offs, but they also have more infrastructure than you do for the same price.
Email is just one of those things I would rather outsource.
