Continuing the discussion from Digital Ocean is blocking outgoing mail! : It seems that Digital Ocean is blocking out bound SMTP traffic for at least some customers. My guess is that soon you’ll have to jump through hoops to be able to access a remote SMTP port. Simple solution: Mailgun, Sendgrid, a…

[صورة] pfaffman: I’ll include a link to this post in my next exchange with them. OK then, let me give you the full spiel, then: Port 25 outbound is an obvious candidate for filtering, because if you can hit the Internet on port 25, you can deliver e-mail to practically anyone. If that e-mai…

I’ll submit that next time I get to a computer. I suspect it’s new accounts that are getting filtered, which is a significant proportion of my installs. A while back, mailgun started requiring credit cards; I told people to give credit card numbers. I can’t suggest a fix here (Other than use 2525). …

[صورة] pfaffman: adding a simple “can we connect to the smtp server at all” test still seems like a reasonable idea. Probably fine to quick test the 587 port during setup and warn if it is not working, but that is not what was proposed in first post.

I had some emails forwarding through my server (at DO) and they indeed got blocked. Nothing related to Discourse. But they are indeed cracking down on some servers and they are going by the policy shoot… then ask. So we had to go through all these hoops to get our email back. Just my 2c

Well, I can’t say this is new: [image] This was on 2014-12-25, and I didn’t get my Discourse for Christmas.

Not new, but I’ve not seen it until now, and the install that I just did. . . root@online:~# telnet smtp.mailgun.org 587 Trying 50.17.85.209... ^C root@online:~# ^C root@online:~# telnet smtp.mailgun.org 2525 Trying 52.24.219.230...

[صورة] pfaffman: Not new, but I’ve not seen it until now, and the install that I just did. . . Yeah, they say it depends on your context. If you come from a 3rd world country IP, you get all sorts of problems like that. At OVH I can’t even get a server. It’s like credit, DO will analyze all …

[صورة] Falco: It’s like credit, DO will analyze all the info they have on you, and if you check enough boxes, you are a potential spammer / abuser and gets a different config. Could we sue then for this prejudice against us? :wink: Just kidding. But indeed I got blocked here. So that’s prob…

Lovely explication, @mpalmer . Crickets from Digital Ocean. I’ve changed my install script to use 2525 since there’s no easy way to tell whether 587 is blocked (my script blindly pipes values into ./discourse-setup so that I’m continually making sure that it’s working correctly). It appears that pe…

[صورة] pfaffman: I propose these changes to discourse-setup changing default SMTP port for those services to 2525. adding a test (e.g., nc -z -w5 smtp.mailgun.org 25) to see if the chosen SMTP port is open Why those 3 services services? They’re the ones that discourse-setup currently knows ab…
