Greetings Peter! I've had no issues with Gmail generally, but I have had infinite troubles with Outlook. Although the DKIM signature appears valid to Gmail and other providers, Outlook insists that my mail has an invalid DKIM signature. I can't remember the last time Outlook.com has not marked email from my domain as spam. But the mail generally gets into Gmail's inbox just fine.
PS: Thanks for your Book of PF! That and your free guide floating around on the Internet has been a big help to me. -- Aaron Lin j...@ircnow.org IRCNow (https://ircnow.org) On Thu, Jul 31, 2025 at 12:57:49PM +0200, Peter N. M.
