blocked emails and email best practices in software design

I'm going to do what I should have from the beginning and disable all types of emails except something really basic like: new join request, delayed publishing failed, etc.  why?  I'm staring at about 80 bounced emails

anyone had experience reversing this?  the last time I reversed something like this it was a google blacklisted a domain, but this is different.  

and before you tell me to just use the smtp mailer that's not really a solution, and neither is changing my static IP.  read on, because this is something that affects all of us, given the current dynamics of the default settings.   it would be good to adopt some kind of best practices around this and incorporate them into the roadmap.  

anyone wanna chime in and tell me their thoughts on this situation?

Because unfortunately for most people, they will mark an endless stream of emails as spam, rather than figure out where to turn them off.  ..Obviously, this causes issues not only with retention, but bounced emails on the admin end, extra time deleting them, and can be entirely avoided by adopting some kind of sensible metrics for the default set of emails una sends, instead of "oh hai, look a firehose! let me drink from it," :-D

what would be nice is to find the RFC that addresses the email / CANSPAM draft spec from the iEEE, so I can figure out how to modify my installation to be more in line with that, because while we all probably hate hotmail and msn equally, those places are not run by incompetent engineers, and their rules have blocked emails from una..  soooo....

    • Well, I looked for this year 2020, the rate delivered is very reasonable I think. Most of the blocked emails are bogus addresses used by net scammers, so it doesn't matter. All my notifications are activated by default except for new likes for people we follow. What do you think?

      • i tried to resend conf email to a few folks i know personally who didnt confirm.   i get now 300+ emails about bouncing..  domains hotmail msn live, heres an example
        <withheldforprivacy@msn.com>: host msn-com.olc.protection.outlook.com[104.47.36.33]
        said: 550 5.7.1 Unfortunately, messages from [208.97.xx.xx] weren't sent.
        Please contact your Internet service provider since part of their network
        is on our block list (S3150). You can also refer your provider to

        • I wonder if "Authenticating Domains with SPF & DKIM" does not play an important role at MSN, Hotmail etc ... Which smtp service do you use?

          • Yes I am using mailjet too and all my problems disappeared at once.

            • I had the same experiences with Hotmail and sisters.

              Only one of our users, instead of setting her notifications, she found an easier way and reported all incoming emails from our site as spam.

              We could never heal the damage and return to a normal state with Hotmail again and started using a SMTP provider.

              • ....is on our block list (S3150). You can also refer your provider to....

                This is the problem, your IP or domain is in their block list.

                • I talked about this with my provider and she said that if you are running your own mail server to make sure you have rDNS, SPF, DKIM set up.  You may have to request the rDNS with the company that provides the IP address.  The SPF is a text record in your DNS server for the domain; there are SPF generators on the net. She also mentioned that if you are on PLESK that they will default the mail server to an open relay; that will quickly get you banned.  Never run a mail server as an open relay.

                  • thanks Will Monte , i will look up the acronym soup you provided for the ones i dont know.   im pretty sure my thing is set to the hilt, because its a managed image, that i have the ability to disable, and just tweak everything on the server, but i will look.  ...    thank you.  and yeah, never never never open relays.  i know for sure i am not doing that.    text copied and pasted for later research.  thanks again :)

                    • i use dreamhost and it runs on 587 via ssl or tls or password.  full email addresses as the username.    hmmmm  this is a VERY interesting guide... i can likely reverse engineer it.    :)  thank you so much.  i'll see how this helps.  i can easily add dns records, etc.

                      • indeed thats what i saw too.  and this is probably because my site sends out tens of hundreds of messages every time someone sneezes on the site.   and someone was cleaning their email, marked it as spam, and when a few did this, the machine probably learned and decided to mark my IP as spam...
                        the hosting co i go with has nearly 200,000 customers... this is not anything ive experienced before, they are extremely well managed.
                        so i need to get to the bottom of this, and it's not something that is being solved just yet, but you did indeed arrive at the same error I noticed.
                        right now, right now is time to eat dried tart red cherries, and drink coffee.  :D

                        • =\

                          • oh hm.  im not european, i wonder if i can still use it :D

                            • Does anyone know how to implement function so that new users who would like to register can not use hotmail.com, outlook.com live.com and to be informed that this e-mail addresses are not allowed?
