So some spam signups just happened (all [email protected] format e-mail) This caused bounced mail to increase, causing Mailgun to block our domain to prevent it getting blacklisted.
So:
- Mail temporarily doesn’t work
- I closed signups for now
- I will ban the spam accounts
- I will check how to prevent (maybe approval required again?)
Stay tuned.
Edit: so apparently there is a captcha option which I now enabled. Let’s see if this prevents spam. Registrations open again.
Edit2 : Hmm Mailgun isn’t that fast in unblocking the domain. Closing signups again because validation mails aren’t sent
Edit 3: I convinced Mailgun to lift the block. Signups open again.

I was vaguely aware of that, but I’m very glad that you posted this link because I didn’t realize that it was this serious and that it hasn’t been patched! My unit is completely up-to-date with firmware and patches, but I can’t find an actual list of affected models ANYWHERE! I’ve taken a cursory look at my system and it doesn’t appear to be compromised, but I emailed Barracuda for additional info. Thanks for this!
