Summary from [WayBack]‪ Dear #lazyweb, can anyone point me to a modern email server setup (just email) with letsencrypt, some spam filter, multi domain preferably on RHEL/Cent… – Jan Wildeboer – Google+

  • many SMTP servers on the interwebs do not have proper TLS setups, so do not require remote SMTP servers to deliver email with a proper certificate
  • delivering mail via SMTP using STARTTLS with a proper certificate yourself is a good step forward
  • postfix
  • dovecot
  • greylisting (although in practice it does not make much of a difference any more)
  • fail2ban
  • dnsbl (often called rbl)
  • spamassasin
  • rspamd (supports SPF, DKIM and many others)
  • letsencrypt automation can be tough, so here is a small wrapper: [WayBack] GitHub – DrGlitchMX/update-letsencrypt: Tiny script for updating “Let’s Encrypt!” certificates from cron
  • it helps having letsencrypt and the mail server to be on one machine:
    • multidomain let’s encrypt cert that has my webserver name and the mailserver in the Subject Alternative Names field. As both are on the same machine certbot can automatically update it and I just point Postfix and Dovecot to the LE files.
  • Hans-Martin Mosner SMTP as-is is just not suitable for the kind of decentralized mail that you would prefer. You need some mechanism to determine which mail senders to trust and which not. Cryptography is suitable at the MUA level and should be used much more, but at the MTA level, TLS for privacy and SPF(bleh) or DKIM(meh) for sender domain authentication are basically your only weapons -much too weak. The PGP web of trust must be considered a failed experiment – who of your mail contacts uses PGP properly or at all? Ironically the only secure messaging solutions for the masses are centralized.

Things to do:

  • find a proper multi-MX fallback setup guide for postfix

Local Guides Connect – Help Desk – Local Guides Connect

Posted by jpluimers on 2019/02/01

Reminder to self: Local Guides Nederland moved their [WayBack] G+ community over to [WayBackLocal Guides Connect – Help Desk – Local Guides Connect which is part of [WayBack] Local Guides Connect and powered by [WayBack] Powered by Lithium | Lithium.

Since that is not part of any other social media platform I subscribe to, I will likely only see new stuff when I actively go to that place: hopefully that is more than once a year.

Reminder to self:

I was https://plus.google.com/+KristianKöhntopp/ and it was fun while it lasted.This is an active profile, and not a reshare target.

And:

I still need to find a good Android app that handles sharing (I think that is called intent handling in Android land), OS based notifications and easier small screen navigation than the mobile web-site.

For my memory:

What’s new in this update:

It’s time for the first update of the year! We appreciate all your comments sent to us through the App Store, in-app feedback and email; and continue focusing on making this app better with each release.

In this version we addressed the following issues:

  • Added support for the AVC (420 and 444) codec, available when connecting to current versions of Windows 10.
  • In “fit to window mode”, a window refresh now occurs immediately after a resize to ensure that content is rendered at the correct interpolation level.
  • Fixed a layout bug that caused feed headers to overlap for some users.
  • Cleaned up the Application Preferences UI.
  • Polished the Add/Edit Desktop UI.
  • Made lots of fit and finish adjustments to the Connection Center tile and list views for desktops and feeds.

Please continue to send us feedback. We read it all and factor it into our planning. If you encounter any errors, you can always contact us via Help > Report an Issue.

NOTE: There is a bug in macOS 10.14.0 and 10.14.1 that can cause the “.com.microsoft.rdc.application-data_SUPPORT/_EXTERNAL_DATA” folder (nested deep inside the ~/Library folder) to consume a large amount of disk space. To resolve this issue, delete the folder contents and upgrade to macOS 10.14.2. Note that a side-effect of deleting the folder contents is that snapshot images assigned to bookmarks will be deleted. These images will be regenerated when reconnecting to the remote PC.
