Hello, I'm having some difficulty seeing list posts from some domains, notably protonmail.com. When viewing the web list archive there is a mismatch to what arrives in Thunderbird. Yep, I've checked "spam" etc. Also, the plug-announce and plug-talk lists do not seem to match the email/password credentials of the plug lists. Take a peek when you get a chance. No hurry.
I also tied emailing the list emails listed on mailman and password reset reminder, but these all kick back host mail.pdxlinux.org[69.168.62.104] said: 550 5.1.1 <mail...@lists.pdxlinux.org>: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command) for all three. -Ed
