I enjoy InvoiceShelf since I migrated to it in December 2024. InvoiceShelf is open-source invoicing software. I do not allow it to send emails, but I’m exploring the idea.
How to prevent local web apps from sending emails
I run MailHog. It’s an open-source email catcher that allows me to see what emails sites running on my computer have tried to send.
Configure InvoiceShelf to use MailHog
Go to Settings > Mail Configuration.
- Mail Driver: smtp
- Mail Host: 127.0.0.1
- Mail Port: 1025
- Mail Encryption: none
