Cloudron's email server

[d19dotca]

@msbt Honestly a lot of it has to do with the fact that Google (in particular) but also Microsoft and others pretty much are at a point where they mark email from any IP they haven't received email from yet (or not enough of it) as spam/junk. Typically it'll still arrive but at the junk box, at least in my experience. But after a few months of sending emails, my emails no longer end up in junk boxes anymore, even to people I haven't sent to yet. So it takes persistence. You can definitely use the built-in SMTP server, but it takes that persistence for a few months.

Unfortunately, that isn't feasible in many cases so if you can't afford to wait months then third-party SMTP servers are your best bet. In my experience unfortunately though I've had a number of issues with a few of those too so I eventually opted to have full control and own my own SMTP server and work it until it was recognized by Gmail, Outlook, iCloud, etc. and thankfully it worked well (after a lot of waiting, haha).

FWIW, Cloudron.io email is hosted on a Cloudron

You must send a lot of email from the same IP because the https://gmail.com/postmaster/ need a few thousand of email every months to consider your IP/server has a mail server

but I'm glad to hear than with a good IP (from OVH) it's still feasible.

@JOduMonT I definitely don't send that much, haha. Maybe a few hundred from my server between all the users on it, and even that's probably a stretch since not all of those would be addressed to a Gmail box. What you're stating must not be a requirement though otherwise I'd have definitely never made to a Gmail mailbox. haha.

I assume there a lot of factors that go into it, the biggest I believe is following as many best practices as you can from this page, and having Gmail users whitelist / mark as not junk your messages so that it'll eventually tell Google it's safe, as those aren't per mailbox and generally feed into Google's spam logic for everyone.

@msbt I second sendgrid. Easy, awesome, free. Bullet proof so far.

You misunderstood, I went away from sendgrid because of shared blacklisted IPs, my Cloudron IPs were fine. But before that, it was working flawless.

@d19dotca yea I've read about that and tried a few weeks, even months, but my customers don't have that much volume, so there's no chance to ever get whitelisted by the big players.

I‘d be careful with Mailjet... https://forum.cloudron.io/post/8901
They don’t notify you when they stop relaying mail.

What was the reason for them to stop relaying? I'm using webhooks to catch events for blocked emails, but that probably doesn't cover stopping their services at a whole.

Actually this is all about sending mails it seems (which is the most problematic part though) but sending mails would already be done by OPs Cloudron, regardless whether Cloudron manages his mailboxes or not.
Also I would not say that we recommend mail server usage only with a relay, it very much depends on the circumstances as already discussed here.

Personally I also host all my mailboxes on my personal Cloudron, up until recently also sending directly out of there, however recently I moved everything to a home-server and now the relay support comes in handy

This was their response after I opened a ticket - mind you that is 5 days after they stopped relaying mails without informing me and with a volume of maybe 10 mails a day received / sent:

that's odd, so were you running a mailing list or was that just their assumption?

No, nothing of the sort. They didn't tell me their assumption. As I said, I had maybe 10 emails a day being sent.
If you look at trustpilot, there are many more with similar issues: https://www.trustpilot.com/review/mailjet.com
