Nov 2, 2026, 11:17 PM@agentultra That's all a huge part, yes; There's other weirdnesses too. I'm happy to provide a second set of eyes.

@agentultra It's all in a very lossy format called "I'm ADHD and have been doing this for twenty years, describe your problem."
Which is why I'm offering to help when an issue is identified. - Woke Leftist Trashagentultra@types.plNov 2, 2026, 11:26 PM
@aaron Ah very good. I do a bunch of other things. My DMARC policy is set to reject. I use spamassassin. fail2ban. I don't relay any mail. No password logins, all SSH.
I only have occasional problems getting mail delivered. Usually when my IP range ends up trapped in a temporary blacklist.

@agentultra Honestly compiling a best practice guide / wiki / knowledge base type thing isn't a bad idea. As long as it doesn't turn into another broken thing like StackExchange.
Nov 4, 2026, 7:05 AM@aaron @agentultra, I'm so glad to see there are more people doing this! Compiling a guide would definitely be a good thing, but just compiling it is not enough: it should be maintained and updated as things progress and change.
I too am self-hosting my email and am absolutely pissed that delivering to #GmailIsNotEmail is a royal pain in the ass: even if Google's own Postmaster Tools indicates full compliance, my emails to people I hadn't contacted before often ended up in their spam mailbox without me or them knowing. At the same time, "deliverability analysis" would not report anything due to "too low level of incoming messages". I ended up setting up a cron job just to send emails to my Gmail mailbox a few times each hour in order to overcome the volume issue, and now at least that complaint is gone (funny, the analysis now says that over 0.1% of my messages are marked as spam, even though their own Spam dashboard indicates no such thing).
As for DMARC, I'm using a free service from Postmark: they receive all my DMARC reports and send me a weekly email with overall stats for the week. For me, this has been working fine for quite a while.

@agentultra Oh it's worth looking at the DMARC reports.
There needs to be a reasonable parser those, it's all XML ( ewww. ) I don't have time myself.
