Switching eMail List Server for LCTG

How it used to be, using Yahoo Groups

  • Yahoo Groups email list
  • Yahoo Groups maintained history of email messages
  • Yahoo Groups held posted presentation files
  • We had thought about switching away, always too much trouble, no real reason to switch
  • Steve set up a Wiki page containing presentation videos and materials
  • Everything was working OK and we could worry about other things (what's for dinner, etc)

So why did we need to change away from Yahoo Groups?

  • Yahoo pushed the point!
  • They announced they'd stop providing many services late last year (2019)
  • They'll stop storing email messages and delete older ones
  • They'll stop allowing file storage and delete ones stored
  • They'll change the way the email list works and how it's managed
  • As of the end of 2019, they have deleted all files and message history from YahooGroups

What Could We Do?

When we learned this what YahooGroups was planning…

  • We formed committee to discuss alternatives
  • and Steve's Mailman service & Wiki were considered
  • We perceived costs associated with switching to
  • We noted No costs other than sweat for switching to Steve's Mailman and Wiki
  • Steve was willing to put in the sweat to effect the switch
  • Committee decided to give Steve's option a try
  • Committee agreed that we could switch to another option later

How was the transfer effected?

Protect the past and set up for the future

First...Just-In-Case actions

  • Steve grabbed a list of YahooGroup emails and names
  • CharlyS grabbed the presentation files from YahooGroup
  • Steve grabbed the entire YahooGroup message history

And we have a bunch of files. Now need to make them useful and replace YahooGroup functionality.

Set Up the Replacement Mail List

We had a list of all members on the YahooGroups list.

  • Created a domain
    • actually it's a Subdomain of
    • Note that is a domain owned by Steve, it can be short for “TO Keep Up with US” (maybe?)
  • Created an email list,
  • Configured the email list settings
  • Converted the email addresses CSV file from YahooGroups to a list consisting of name needed for Mailman
    • Banned members - some were banned on YahooGroup, and were set as banned on Mailman
    • Digest - some members had daily digests of messages on YahooGroup, set this for them on Mailman
  • Did a bulk add of all emails into Mailman using this converted file

At this point, the email list was operational.

Tweak it

After it was deployed (put into operation), Steve made tweaks (fixes, improvements) to the configuration, for example:

  • Remove/eliminate bounce processing
  • Changed email header line to [Lex Computer & Tech Group/LCTG] (from [LCTG])
  • Set moderators as Steve, CharlyS, and JohnR. What are moderator's duties?
    • Moderate (approve or deny) posts by non-list-members (e.g. spam)
    • Process and approve (or not) requests to join the email list (also prevents improper use)
    • This is a low-overhead job (maybe 1 join request/month, maybe 3-4 message moderates/year)
    • Anyone else want to be a Moderator?

Posted Files from Older Presentations

We had a directory with zillions (figuratively) of files from presentations, want to make 'em available somehow

  • Wanted ease of use to see what's there and access stuff you want
  • Decided to put these files in the Wiki
    • decided against FTP server
    • decided against using cloud storage e.g., Google, Dropbox
  • Uploaded presentation files from 2007 to 2018 to the Wiki
  • Created a Wiki page that…
    • shows all of the files by year
    • links to each so you can view or download them by clicking
  • Linked to this page to the LCTG main page on the Wiki
  • Note that recent presentation files are on the Wiki and not on this “older files” page

What About the Email Message Archive?

  • We have a large file holding old email list messages (100MB+)
  • Messages are in a raw format, hard to read by most humans
  • Message file needs processing before you can search and read messages (unless you are a Super Whiz)
  • (See an extract below)
  • We are not doing anything with these for now
  • If you would like a copy of this message archive, let me know
  • If you would like to help process the messages or extract useful ones, let me know
  • But is it worthwhile? Is there sufficient benefit?

LCTG Information Page -- the Wiki [[]]

  • Nearly 2 years ago, Steve created a Wiki page holding information:
    • About the computer group (LCTG)
    • About upcoming meetings
    • About past meetings with link to video recording and presentation slides and other materials
  • Over time he has enhanced this Wiki:
    • Adding info on how to join the group
    • How to see past email messages (Mailman system)
    • How to access past presentations

Using the New Technology

Using the current (new) system; you'll find the links here at the bottom of every email you get from the list.

Email list

  • Send to the list – send email (from a subscribed email address) to or
    • Sends from non-subscribed email are Moderated
  • Reply to messages – go to sender of message only
  • Reply to message going to everyone – Reply All
  • View message archives – go to
  • Sign up for the email list – send email to (this can be you if you're not on the list, or a friend) and include
    • your full name
    • town where you live
    • brief intro and why you're interested in the group, and
    • topics you might present to the group
  • Get off the email list – send email to from the email account you want to unsubscribe
  • Change your subscription
    • see the link to see/change your list options, at the bottom of emails sent to you
    • For example: (if you are subscribed as
    • On this, your membership (subscription options) page, you can
      • get your list password sent to you
      • change your list password
      • change your email address
      • turn on/off batch (digest) mode
      • turn on/off message delivery
      • get an acknowledgement whenever you send to the list

Presentation files

Behind The Curtains

Some more technical information for those with inquiring minds

The email list CSV format (example) received from YahooGroups

"Display Name",Email,Status,Delivery,Posting,Joined
johndoe,,Member,"Individual Emails",Allowed,"August 31, 2011"
Albert Einstein,,Member,"Individual Emails",Allowed,"November 13, 1938"
Dinald Trimp,,Member,"Daily Digest",Allowed,"January 20, 2017"

What it was changed to for entry to the new system

johndoe <>
Albert Einstein <>
Dinald Trimp <>

After the email addresses were read into Mailman, Steve manually changed subscriptions for those banned and those getting a daily digest.

Wiki page extract

Here's what part of the LCTG Wiki page looks like (the table holding past and upcoming meetings)

^ Date^ Topic^
|Jan 1, 2020|//New Year's Day -- no meeting//\\ Your homework this week is to pray (to whichever deity you prefer) for health, wealth, and happiness in the new year.|
|Jan 8, 2020| **Ig Nobel 2019 Awards** //awards for dubious inventions// (Peter Albin)  [[|presentation]] [[}|link to Improbable Research page]]|

How Mailman is Administered?

The list administrator can make changes to the way the list operates and membership data. The user interface provides many pages grouped by function:

  • General Options
    • See/change Group name, Administrators, Moderators, Descriptions of group, [ ] message tag, etc
  • Membership management
    • List management (manually unsubscribe, set moderation, don't sent messages to, etc, for specific members)
    • Subscribing and removing members
  • Archiving options (our messages are archived, available only to members, creating a new volume of messages every month)

Opening PDFs

A How-To, from Gary Patrick

  • Click on the 3-dot “Customize Chrome” icon near the upper right corner of any Chrome page.
  • Select “settings” and open the “Advanced” portion at the very bottom.
  • In “Privacy and Security,” scroll down to and click on “PDF documents.”
  • Slide the “Download PDF files . . ” button to “Off.”

Extract from messages archive, 101.1MB total

This shows that the archive isn't really useful as it stands.
