Dashboard: Invoices – Proton Account

Posted by jpluimers on 2025/12/15

For the yearly administration shizzle, the direct link to Dashboard: Invoices – Proton Account (account.proton.me/u/dashboard#invoices) where sometimes you have to visit one of your product first.

The reason is that at the time of writing, this was documented to be in a different place, as per [Wayback/Archive] How to download, customize, or pay invoices | Proton

Log in to your Proton Account at account.proton.me on a computer, click Settings → All settings → Dashboard, and scroll down to Invoices.

You start at [Wayback/Archive] account.proton.me/login and end up at account.proton.me/apps and that is where you cannot choose settings. You can however go to individual products and via that to the above invoices link. That’s cumbersome, it is way easier to just follow that invoices link, but in case you want to go via the products, these are the steps to follow:

“Skiff – Private, encrypted, secure email – 10 GB free” was too good to be true: discontinued (“sunsetting”) at 2024-08-09

Posted by jpluimers on 2024/04/09

Skiff (email service) – Wikipedia already mentioned them as too good to be true for a while:

It launched in 2021 and was developed in San Francisco, California. In November 2023, it reached its own record of almost 2 million users (17 months since launch).

…

In a 2023 article, PCMAG reviewed Skiff pointing that Skiff offers “End-to-end encryption for email, collaboration, and calendar”, making complements to the fact of its services being free and easy to use (while being available as Apps for macOS, Android, and iOS).

This was all in the midst of me trying to find another place for our mail than GMail, and I am considering Proton Mail (which is profitable and offers both paid and free plans).

I had heard about Skiff Mail, and was lucky to not have included them on the shortlist as mid February, the above Wikipedia articled was updated to contain these two sections:

Why can’t we have nice things: ZorgDomein email subject has no ID in them, nor responds on Social Media on improvement suggestions

Posted by jpluimers on 2023/12/13

The drawback sending out emails all with the same subject is that the receiver is having a hard time setting them apart.

Especially in the work or medical realm this makes people miss crucial information.

Worse are organisations broadcasting on Twitter, but not responding at all to improvement suggestions. [Wayback/Archive] @ZorgDomein / Twitter gets both wrong (and is also unusually hard to find phone contact information for on their web-site):

Email Handling and vBulletin Cloud – vBulletin Community Forum

Posted by jpluimers on 2023/08/25

For my link archive: [Wayback/Archive] Email Handling and vBulletin Cloud – vBulletin Community Forum.

  • Asking your end users to white list your email address and the Sendgrid IP (167.89.58.99) can help alleviate the issues.

I didn’t know the above but bumped into an issue because I didn’t know a supplier had moved to vBulletin Cloud, my account password stopped being accepted and my account password reset messages would not arrive.

So I wrote this as part of a mail to sort this out, and it was confirmed to be correct:

Then I re-checked a few connection refusals that appeared close to the password reset tries. Not sure if this a pattern, but a few of them had this:
2022-02-20T19:41:42.999415+01:00 snap sendmail[24314]: NOQUEUE: connect from o1678958x99.outbound-mail.sendgrid.net [167.89.58.99]
2022-02-20T19:41:43.015958+01:00 snap sendmail[24314]: NOQUEUE: dns 99.58.89.167.bl.spamcop.net. => 127.0.0.2
2022-02-20T19:41:43.016442+01:00 snap sendmail[24314]: ruleset=check_relay, arg1=o1678958x99.outbound-mail.sendgrid.net, arg2=127.0.0.2, relay=o1678958x99.outbound-mail.sendgrid.net [167.89.58.99], reject=553 5.3.0 Spam blocked see: http://spamcop.net/bl.shtml?167.89.58.99
2022-02-20T19:42:29.527789+01:00 snap sendmail[23814]: 21KIeTfo023814: engine10.uptimerobot.com [69.162.124.231] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
From the linked page I got to https://www.spamcop.net/w3m?action=blcheck&ip=167.89.58.99 indicating

167.89.58.99 listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 13 hours.

Causes of listing
  • System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Express-delisting is not available

Listing History

In the past 44.4 days, it has been listed 12 times for a total of 13.3 days

Can you check if the forum software uses sendgrid?

The confirmation linked to the first post in this blog entry on how to whitelist the SendGrid outgoing IP-address.

One thing I wonder: why does SendGrid use a single outgoing IP-address? If it gets blacklisted, many of their clients have problems.

Anyway: before adding the entry to my whitelist, the problem had resolved itself, and the blacklist entries were done:

Some notes on forwardemail.net

Posted by jpluimers on 2021/12/01

Some notes, as I’m looking to a stable, simple to maintain email forwarding system that is also secure and – yes – can cost money.

I need to leave IT-infrastructure behind that is easy to maintain for my heirs.

Some links:

  • [Archive.is] mausdompteur 💉 on Twitter: “Email! Yes, Email. Need to Set Email for a domain, basically forward only. Has anyone ever heard of https://t.co/v29TbMXrrl? Is it good? Any alternatives I should consider?”
  • [Wayback] The Best Free Email Forwarding Service for Custom Domains | Forward Email

    The best open-source and free email forwarding service for custom domains. We do not keep logs nor store emails. We don’t track you. Unlimited aliases, catch-alls, wildcards, API access, and disposable addresses. Built-in support for DKIM, SRS, SPF, ARC, DMARC, and more. No credit card required.

  • [Wayback] FAQ | Forward Email has a truckload of information, but the main points for me are these:

    What is the max email size limit

    We default to a 50MB size limit, which includes content, headers, and attachments. Note that services such as Gmail and Outlook allow only 25MB size limit, and if you exceed the limit when sending to addresses at those providers you will receive an error message.

    An error with the proper response code is returned if the file size limit is exceeded.

    …

    What is the difference between Free and Enhanced Protection

    The Free plan requires you to use public DNS records to store your forwarding configuration. Anyone with a computer can lookup your forwarding configuration in a terminal if you are on the Free plan. Unlike the Free plan, the Enhanced Protection plan uses a cryptographically generated random string to store your forwarding configuration privately.

    Free Plan Enhanced Protection Plan
    forward-email=user@gmail.com forward-email-site-verification=m8d7o8K4Il
  • [Wayback] About | Forward Email with this very important point for me:

    Privacy

    We have a “zero tolerance policy” privacy policy, which states that we don’t store logs nor emails, and we don’t track users. Our statement clearly states that we do not collect nor store forwarded emails, metadata, server-side nor client-side logs, IP addresses, or browser information.

    Only an email address is required to create and configure the Enhanced Protection Plan, which hides DNS email alias information on the free plan through a managed and hosted service.

    User’s accounts, domains, and all related information can be permanently deleted at any time by the user.

  • [Wayback] Pricing | Forward Email (levels: free / enhanced protection / team / enterprise)

    Free email forwarding for domains with features including Custom Domain Email Forwarding, Disposable Addresses, Multiple Recipients, Wildcards, and more!

  • It’s open source too (written in JavaScript using Node.js), but running it requires you to keep up with versions and security: [Wayback/Archive.is] forwardemail/free-email-forwarding: The best free email forwarding for custom domains. Visit our website to get started (SMTP server)

The horrors of HTML email where there CSS

Posted by jpluimers on 2021/11/16

[Archive.is] Kat Maddox on Twitter: “Who’s the CEO of emails I need to talk to him… “:

This is why dreamweaver still exists.

[Archive.is] Kat Maddox on Twitter: “You don’t need a time machine to go back to the past. You just need to try to write HTML in emails. If I have to nest one more table, I’ll have gone back far enough to be able to warn people about the dot com bubble. Fuck it. I’m writing this newsletter in markdown”

Markdown with an HTML generator actually is quite a good way to get HTML emails going.

Another route is [Wayback] Foundation for Emails | A Responsive Email Framework from ZURB.

Oh remember this: [Archive.is] StuAngel on Twitter: “rule of thumb “the mail clients are about 5 years behind in HTML support” – that was like 10 years ago and they have never gotten any better… https://t.co/lVAW5YCubm”

Common SMTP message size limits

Posted by jpluimers on 2020/04/08

After a 2018 discussion with a “zorgkantoor” (Dutch for office that arranges for special long term health care needs, successor of AWBZ) about their very low (10 megabyte) SMTP message size limit – even though they expect scanned PDF documents.

Their web-care team posed this limit as normal, so I made a list of limits in their peer group, common world-wide and well-ranked Dutch internet providers.

My plan is to check the progression of these limits over time.

Note these are the bruto message sizes including encoded attachments. Since encoding in [WayBack] MIME Base64 – Wikipedia has a overhead of at least 37% (encoded size is at least 1.37 the original size), the unencoded maximum size is less than 73% of what is listed below.
