Mailgun – transactional email/SMTP relay

Recently I’ve stumbled onto Mailgun, a transactional email service targeted at developers; they provide an API to easily craft and send email messages through their service. You can verify your domain with them using a few TXT records and once configured, you can send emails using your own domain. Currently, Mailgun allows up to 10,000 emails per month for free; adding your credit card info to your account unlocks 30 days of log retention (instead of 2 days) and allows you to add up to 1000 domains. They also provide an SMTP relay that uses ports 25, 2525, 467 and 587 and it supports SSL/TLS or no encryption. There have been many times where I tried to configure Scan to Email on an older multi-function printer; most of the time it didn’t support SSL/TLS for email and there was no on-premise Exchange or other email server to relay with. Having something like Mailgun back then would’ve been nice. Now that I’ve found Mailgun, I was able to delete a spare Google Apps account that I was only using to send email notifications for my computer backups and Synology NAS.
