Why I replaced MIT with copyleft license for Nodemailer

“I understand the switch to copyleft, but the EU's own website explicitly lists GPL licenses as incompatible, in the matrix on this page: Dual-licensing under the EUPL and GPL, with the option to choose either, would be helpful. Otherwise Nodemailer is incompatible with the…”

Why I replaced MIT with copyleft license for Nodemailer

“Speaking from my corner of a large organisation, this is pretty spot on. $100-300 is "no brainer". LDAP/AD, OAuth is major plus. Support SLAs tiers are also something we would look for, even in Open Source. We don't use Nodemailer, but we might now that I know about it. I'll see…”

Postal: Open source mail delivery platform, alternative to Mailgun or Sendgrid

“Is this more than an SMTP server? Those are services designed to send emails as an API service for many different parties. Is that what "Postal" is? Or is it a another SMTP server like Postflix or something? It's not at all clear from your description...”

ZLibrary domains have been seized by the United States Postal Inspection Service

“Maybe the Postal service is where the copyright owners had enough friends to go after z-lib.”

Preview emails with letter_opener, MailCatcher and MailHog

“hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails). MailCatcher ( ) and MailHog ( ) are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a…”

html email rendering as plain text

“When MailHog receives an email, which is html, it renders it as "plain text". I don't know why this happens, and how to render it as html. Here is an example of part of the headers, as well as a screenshot: ``` Content-Transfer-Encoding: quoted-printable Content-Type: text/html;…”

Mailpit – An email and SMTP testing tool with API

“My work machine is prohibited from connecting to port 25 outside of the accepted work systems. When on VPN, I can't even connect to port 25 within the local networks. docker run -d --name=mailpit --restart unless-stopped -p 8025:8025 -p 1025:1025 axllent/mailpit I can connect to…”

Mailpit – An email and SMTP testing tool with API

“Same, I'm using it in CI/CD for full E2E tests of web apps in combination with Playwright for app interaction, and it's awesome. Same test flow can nicely simulate user interactions and verify that emails with the correct content go out from the backend, all in seconds within a…”

Himalaya: CLI to Manage Emails

“I think the README is missing some examples of what this can do. I used it for a script that marks every mail as seen: #!/bin/bash while true; do # Run the command and capture its exit code result=$(himalaya envelope list --folder INBOX --page 1 --page-size 100 --output json not…”

Himalaya: CLI to Manage Emails

“Genuine question - the HN title says "CLI to..." but looking at the GitHub repo I don't see any CLI-centric documentation. I do see $ himalaya envelope list --account posteo --folder Archives.FOSS --page 2 and a screenshot that looks like PINE. Is that screenshot interactive…”

How can I implement service-to-service authentication with Office365 using the OAuth2 SASL mechanism?

“Hi, I am trying to send email from a server application via Office 365 using OAUTH2 using MailKit with the client credentials flow. I have tried to resolve for several days so as not to waste your time - but am now admitting defeat. Here's the code I have so far: SmtpClient…”

Support for CoreCLR

“Will there be any support for the new core clr? Also, it would be sweet if we could configure this library with smtp defaults via environmental variables as this is a part of vnext.”

I've created a fork with improvements & PR merges

“Hey all — I've created a fork of this project with various improvements and also some PR merges. You can check it out at [ I've created my own fork because this project seems abandoned, and I wanted some of the features that were not implemented (mostly persistent storage and…”

Mox – modern, secure, all-in-one email server

“set this up today, the documentation is useful and the quickstart very helpful, the dns stuff pretty much works exactly as it's supposed to and is just a bunch of copypasting (in my registrar's ui). specifically for mox there was some things i would have liked to see: explain…”

Mox – modern, secure, all-in-one email server

“After 21 years of hosting my own email server, starting with roll-your-own (anyone else remember sendmail.cf?) and moving to boxed solutions such as mox or mailcow, I gave up. Maintaining IP reputation and keeping up with the neverending set of arbitrary rules (spf, dkim, etc) I…”

Haraka - a Node.js mail server

“node.js is Evented I/O. It might not be a perfect match for mail server. Not like in Comet or other similar situations, SMTP sessions are highly batched and not that human-interactive. There might be very little inactive open connections on a typical mail server. But based on…”

Haraka - a Node.js mail server

“Nice. Looks like a Node.js port of qpsmtpd - Edit: Just found that author has noted that Haraka is quite similar to Qpsmtpd.”

Paid Cerberus 'lifetime' licenses are expiring

“Cerberus also allows you to do things such as set off an alarm on the phone, take a photo using the camera, and a few other things. I don't think Google's solution does all that. In addition, a quick test looks like using Google's service triggers a notification on the device,…”

Paid Cerberus 'lifetime' licenses are expiring

“>> Quite frankly we did not think Cerberus would last that long! Oh, I get it. When they said "lifetime license" they meant Cerberus' lifetime, not the user's lifetime. They just somehow survived longer than they thought they would. /s”

Go implementation

“I am currently working on a Go implementation in my fork and most of the code and tests are done. The problem I am facing is how the code for each language implementation is generated from a template. For example, in the Go implementation, we would have `mail_check.tmpl.go`…”

[QUESTION] Is there any way to dynamically require net-smtp for ruby 3?

“I understand that a lot of classes net-smtp, digest, and others have been moved from builtin classes to gems in Ruby 3. As a result of that truemail now requires net-smtp as a dependency, which in turn requires digest as a dependency. So when loading truemail v2.6+ on an app…”

[FEATURE] Question about server behind load balancer

“Hi, first of all thanks for the gem! It is really useful. I can't find where I can ask question except here. I'm not sure how to perform SMTP validation when server is behind load balancer with internal IP only. `Truemail.host_audit` always fails because server doesn't have…”
