This thread got me checking logs and I just spotted several of those "deferred due to user complaints" tags. And compared to them, we're tiny. Don't know if it's widespread, but it appears you are not the only one so blessed.

We've seen this before too but this week it has been different. Every single host that relays email on our network has these in the queue. Now a couple of them do mailing lists and such so I could see it happening but a couple of them don't do anything high volume at all.

For some of them some mail goes through but only some of the time. It seems like if we hit the right MX machine it works and other times it does not.

We tried going around them by sending mail over to an employee's personal mail server (which does nearly no volume at all) but even it is blocked probably 1/2 the time.

I'm not sure what is going on but given all this I can't believe it is just "normal".

We filled out one of those forms but just got back a response that said it wasn't happening but if it was we should see their "best practices" URL. Only problem is we actually do everything on their list (including both DomainKeys and DKIM).
