New mail submit service for Librem One users at ms.librem.one

We have setup a new mail submit service for Librem One users at ms.librem.one. To use this server, just replace smtp.librem.one with ms.librem.one in your mail client sending mail settings.

This server runs on latest debian gnu/linux stable version trixie, has latest postfix/opendkim and other libraries. Once more people test and confirm it is working well, we intend to point smtp.librem.one domain to the new server.

This update is part of tightening mail server configuration to prevent spoofing and spam.

This is an early call for testing the new server, so if you have a Librem.One email account, please test the new server and let us know if you find any issues.

Because of a gaming club that I belong to sends uses address lists .gt. 60+ odd recipients, it already means I can’t do reply-alls and I switch my replies to gmail.

Does this tightening of the email server lower that number again?

I haven’t seen a mass spam in years as it seems they target one addresee at a time. I think the recipient limit is a red herring now.

For now I have kept the maximum recipients limit same as the old server - 50. I’m discussing with the team if we can increase that limit.

I think you are correct. Any recipient limit should be a rate limit on total recipients regardless of whether the recipients are distributed as

  • one email sent to 60 recipients
  • 60 emails sent individually to each recipient
  • anything in between

but there should be some limit.

Regardless though the judgement call on this restriction is a difficult one. If Purism gets marked as a spammer and thereby blacklisted, it will be painful for Purism and painful for all Purism (Librem One) customers.

However

I feel as if your gaming club is not “doing it right” then.

With a mailing list, you should be replying solely to the mailing list and the mailing list host should be doing the fanout to send to every person on the mailing list. The identity (and email address) of each person on the mailing list should be secret (suppressed from view to you and to anyone else on the list). “reply-all” should not even be possible.

Unless of course you are the one managing the mailing list and the mailing list host is (or was) Librem One.

Having said that the identity should be secret, of course an individual contributor to the list may choose to include identifying information, including an email address, within the body of the contribution and in that case the identifying information would cease to be secret.

Some do. Some don’t.

I still see lame spam/scam emails addressed to “Dear Customer” or “Dear Sir/Madam”, which could well have been sent en masse.

But I also see better spam/scam emails addressed to “Dear Irvine”, where they have inferred the name from the email address, which by definition are emails sent one by one.

And the better still spam/scam emails marry up lists of email addresses with data breach material, so that the email is not only personally addressed but includes correct other personal information. (This can still be epic fail though if I am not a customer of the company that this is pretending to be from.)

Unfortunately, I’m not in charge of THAT club. So I can’t go herding those cats. But I like your answer.

(There is another club I’m in charge of and I use groups.io for that, but that’s a different story.)
