Report button doesn't work

I've noticed that when you report a post you get this error:

There was a problem communicating with SMTP: Expected response code(s) [250] but got response []

I'm not sure what it is but the reports never go through. Sometimes this happens when I make posts as well but they usually post anyway.

I was wondering about this have had this happen before on topics and it still shows and wondered if the reports would still go through.

Just noticed this as well when trying to report a spammer - does reporting send an email to each mod and someone's using a broken email address?

I don't think anyone's email is broken; it's worked in the past. It's supposed to send one to each mod but it hasn't been sending anything.

Mail is broken too and giving the same error (I've temporarily disabled e-mail authentication requirements). There seems to be nothing I can do with the administration options to fix this so I'll be trying to get in touch either mha or marcan very soon.

The Report button now works again
