postmark | Golang package for the Postmark API | Email library

I am facing issue in my project, when I pick date from the datepicker calendar there is an error generated, i actually wanted to save my data with an extra input as date, for this purpose I use date picker from mui (material Ui), but I am unable to find any solution or not able to solve this error. I will show some parts of my code to show what I am facing and what I wanted to be solve.

this is the Image of the date picker Calender, when I click any of the number from it, it give me an error, also when I edit the in the field error generated.

There line of error generated are shown below, which I am not understand why it is.

I was new to rails 7.0 as I followed the official guide in website, making the sample blog project.

When comes to the delete single post function. Seems my code still fires a GET HTTP request instead of a DELETE request. I only have one controller which is articles_controller.rb

I had this tutorial working for a different exercise, but now I'm putting the actual work into practice and can't figure out what I'm now doing wrong.

Here's my Product Categories model

after i click register button i get the error bellow Swift_TransportException Process could not be started [The system cannot find the path specified. ] and whene i go to phpmyadmin it seems that i have the new user record in my database i don't know what's the relation between the auth and swiftMailer i already tried clearing the config using php artisan config:clear changing MAIL_DRIVER, MAIL_HOST, MAIL_PORT i don't know what to do

this is my .env file

As stated in the Symfony Docs it is possible, to add a failover configuration for mail servers:

Symfony's mailer supports high availability via a technique called "failover" to ensure that emails are sent even if one mailer server fails.

A failover transport is configured with two or more transports and the failover keyword:

MAILER_DSN="failover(postmark+api://ID@default sendgrid+smtp://KEY@default)"

The failover-transport starts using the first transport and if it fails, it will retry the same delivery with the next transports until one of them succeeds (or until all of them fail).

Is it possible to use and configure this feature in TYPO3? If so, how?

Can other configurations like TLS Peer Verification (Symfony Docs) of the Symfony mailer be configured in TYPO3?

By default, SMTP transports perform TLS peer verification. This behavior is configurable with the verify_peer option. Although it's not recommended to disable this verification for security reasons, it can be useful while developing the application or when using a self-signed certificate:

$dsn = 'smtp://user:pass@smtp.example.com?verify_peer=0';

I am currently struggeling trying to use Postmark with the Symfony5 Mailer Bundle. Although the documentation seems to be clear, i am unable to send any emails.

My first point of confusion is the suggested DSN format for Postmark:

postmark+smtp://ID@default

It seems unclear what ID should be used, as Postmark, for SMTP, provides Username and Password, as well as an Acces Key and Secret Key (SMTP Token). An ID, as requested, is not provided.

Does anyone know what configurations should be used here?

Thank you in advance!

I've got a .Net Core project from one of my colleague that has been managed by .Net SDK 5 and VS Code. But now I want to manage it in Visual Studio 2019, as it is easier to navigate codes and run/debug project. I could open the project folder, by choosing File/Open/Folder... and select the project folder in VS 2019. But when I try to run it by click run button in the tool bar as below, I get the alert box as below next. I clicked this run button to run project Build failed alert message

And here is the build output.

I initially had my mail configuration settings in my .env file pointing to my gmail account and contact form was working fine. I have now changed my settings to point to a webmail and run php artisan config:cache but the mail is still being sent to my gmail. Below is my configuration settings and I've also tested the web mail by sending an email to it via gmail and sending back to gmail from the web mail and it's working fine. Any assistance is highly appreciated.

Here is my weekly Postmark DMARC Digest. I currently have an allow-all DMARC policy. My last 4 weekly digests have all looked pretty similar as far as DKIM and SPF failures.

DMARC Report

I know that Mailchimp can't be SPF-aligned because of the way they configure their service, but it can be DKIM aligned.

As you can see Mailchimp fails DKIM Alignment about 4% of the time. I thought it should be good 99.9% of the time.

Is this normal?

Should I enable a quarantine or reject DMARC policy and lose 4% of my contacts?

Thanks in advance.
