Hi All,
It seems that we're having some problems receiving emails from selected Yahoo! Mail Accounts. I noticed that there is a commonality between the accounts that fails when sending an email to our domain (see email header below)

Sorry, we were unable to deliver your message to the following address.

Um...it might be easier to get mail, if your host didn't close the connection with a 5xx error. :/

I imagine when port 25 stops giving 5xx failure message back, mail reception might improve. ^_^;
