I know this is the wrong place to post this, but due to this problem there are no other ways to contact MR. Over the past week I've been trying to send a manuscript to Model Railroader Magazine at manuscripts@mrmag.com, and my email has repeatedly bounced. I also tried the editorial assistant listed and got the same error message. It seems to be all the addresses in the form of _________@mrmag.com. The error I've been getting has been a 550 550 No such user - psmtp (state 14). I also tried filling out the contact form to let you know about the problem but haven't gotten any response. I assume that's connected to the email addresses too.
Just wanted to let you know that something in your servers are down. If whoever at MR reads this could let the tech department know, that would be great...I still need to get that email through!
