[WriteLog] Problem sending LoTW logs to ARRL

[K2MK]

I use the "Export Trusted QSL File" from within WriteLog to send my contest 
logs to the LoTW. WriteLog generates an e-mail with the following address:

lotw-logs at arrl dot org

I received "unable to deliver notices" for my last two e-mails. Does anybody 
know if the LoTW e-mail address has changed? There's nothing wrong with my 
e-mail server as I've sent many e-mails to other destinations without 
difficulty. I did try to find the current e-mail address on the LoTW site 
but I was unable to locate it.

The LoTW site is not down and there is a link to monitor uploads and they 
have been uploading files steadily. I know my certificate is still good 
because I manually uploaded the TQ8 files directly to the LoTW site and they 
were accepted.

Here's the text from the messages I received:
