Interesting concept.

I tried it out and got the 'We've sent an email to foo@example.com with a confirmation link.' message. It's been about 5 minutes and I still haven't received the confirmation message. You might want to turn some knobs so that the confirmation emails go through sooner.

Or are the confirmation emails similarly intentionally delayed? :)

frits1993 5 years ago | |

Haha no the confirmation mails are sent straight away ;)

"tardamail.com is too new, temporarily blacklisted" is what I see in the mail-logs.

Seems like something I can't do much about at the moment, and should correct itself in a while. It seems to get past most spam-filters though.

I'll consider implementing an email-confirmation backup, thanks!

You might find this useful:

Especially the part about "Rule of Thumb for Running Mail Server on a New IP Address

When you run a mail server on a new IP address, you should not use this IP address to send newsletters (aka marketing emails) right away. Instead, you should use this IP address to send transactional emails for a period of time to improve the reputation.

You may also want to use SMTP relay to send emails for a few days because SMTP relay services have a high IP reputation. After that, send emails directly to the familiar recipients."

Sortof related: I just wanted to add that many MTA's email servers also support this concept. Using milters or scripts, you can default emails to be stored in the hold queue, then release them based on ingestion time.

Cool, I did not know that. Are there any other thinkable use cases of keeping messages in a hold queue for a longer period of time, for this option to exist?

Some sysadmins/postmasters do this to protect against spam floods. They use cron jobs to hold/release emails after validating the envelope contents using tools like MailScanner. Some use that for intercepting test messages [1] I don't have the links handy, but I have also seen some projects in github that utilize hold queues for managing more granular rate limits based on content rather than destination. Some anti-spam tools will also quarantine messages into the hold queue for review.

I'm loath to mention this, but although I assume the use of "tard" in the name is to signify delay, some might be sensitive to that term.

some people are always offended. no matter what. i think its a funny wordplay.

but seriously. if OP wants to already prevent sjw outcry: change the name

Instant messaging has become the standard. The messages I send my good friends have become shorter, and are often based on my expectations of their reply. With TardaMail, I wanted to recreate the letter-writing experience, digitally. Taking more time to write someone without expecting an instant reply can be very valuable, especially in these times of isolation.

How do you prevent spam? You should at least verify the address of the sender.

A favicon would be nice. (I'm using Chrome.)

frits1993 5 years ago | |

Good point, I will push an update with email verification and a favicon in the next hour.

Done!
