What external services do you use for your selfhosting setup? (lemmy.world)

I mean anything that is not hosted in your house. For example, dynamic dns, some type of ddos protection, off-site backups, external oauth provider, etc.

I’d recommend looking again, as I think that advice is becoming dated. Greylist and DKIM make spam prevention super simple, ironically because the centralization of email towards Outlook and gmail has trained pretty much every sender to follow the rules or your email doesn’t go through. And then Greylist catches the rest, because spammers don’t come back and retry after a few minutes.

    The problem isn't incoming spam, but rather not being able to send to the larger email providers because of arbitrary spamfiltering on their side.

    True. I kinda dodged that problem by having a personal .net domain that’s older than wikipedia.org. My understanding is that you can raise your domain’s reputation with some work.

    Honestly the most important thing I use my domain for is easy-to-delete mailboxes and aliases to give to companies and contacts. That’s just incoming email.

    For outgoing, there are services that let you send them an email and receive a report on any mistakes or misconfgurations they notice. I followed the first tutorial I found that didn’t seem like it was just advertising “see how hard email is? Looks impossible doesn’t it? Why not pay us instead.” Ended up being at linuxbabe dot com, run by Guoan Xiao, with part one titled “Build Your Own Email Server on Ubuntu: Basic Postfix Setup”. No links but search engines find it.

    Big difference is I use OpenLDAP/slapd, and I put different components on different VMs. Took maybe a couple weeks of free time here and there, but I’m proud to say my outgoing emails seem to be accepted everywhere. Not that I send many, really.

    Eventually planning on implementing filtering for terms and conditions updates for long-forgotten sign ups. I would like those to bounce.
