SparkPost just suspended the mail account I used with Discourse

Phew

In an effort to keep our systems free of fraud, we employ automated detection systems that suspend accounts based on certain activity and metrics. Most of the time, we find that our system has acted correctly and prevented bad mail from going out. Unfortunately, this automation also rarely catches good customers, and it appears this happened to your account today. Upon manual review, we have reactivated your account. We work hard to maintain high quality mail servers that are free from criminal activity and spam, so we hope you will accept our apologies for any inconvenience this may have caused.

Worth bearing in mind, though - if a user submits an external link that’s genuinely dodgy, your email service provider may pick it up and suspend your account immediately.
