Sorry guys if this is the wrong area to thread in, but it seemed most relevant given hotmail is part of MSN. I today recieved an email from a potential customer who asked a number of queries regarding on how to open account etc.. - it was a genuine query from someone - not unsolicted Junk or business proposition. However I answered their email with a general "reply to" - and received the following: host mx3.hotmail.com said: 550 Requested action not taken: mailbox unavailable (in reply to RCPT TO command) Does anyone know what this means? I know my emails wont send to it - I could understand if it was a virus but it the fact that they wrote specifics in the email means I could potentially lose a customer for simply not replying. Anyone offer an alternative way around this or have had it happen to them? Thanks.
I get them all the time. I believe the mailbox is either offline or just down for right now. Also MSN has a huge effort to cut spam so this could also be related to there spam filters.
Was his email an hotmail account? I had this problem with my server. When someone from a free email (hotmail, Yahoo) tried to send me an email, my server just sent a nice :email doesn't exist along with the code. My engineer found out that my anti spam system was the cause. We changed it to Spam assassin and everything run smooth - I hope
