Email send stopped working

Hi.

As of recently email are not being sent out anymore. Didn’t touch a thing except did the Invoice Ninja updates.

Changing TSL, SSL, ports doesn’t seem to change anything. I can send out e-mail using telenet from ac ommand line.

So what is the very less stressful procedure to test email sending? How should I proceed to troubleshoot.

What I do now…

  • change and save.env file
  • php artisan optimize
  • clear cache
  • resend (email) the exisiting quote

-env settings that used to work before
MAIL_MAILER=smtp
MAIL_HOST=mail.mydomain.com
MAIL_PORT=25
MAIL_USERNAME=payments.mydomain.com
MAIL_PASSWORD=xxxxxxxxxxxxxxxxx
MAIL_ENCRYPTION=
[email protected]
MAIL_FROM_NAME=Payments

Hi,

@david any thoughts?

Wait, it works for new quotes, but won’t resend out old ones. Strange, but it works.

Please ignore it.

Thank you for quick response Hillel.
