One of my regular customers who has a hotmail.com email account did not receive their order confirmation email nor my confirmation emails from within the Actinic ecommerce windows client.
I then receive automated "Mail delivery failed" messages from hotmail.
I can reproduce the problem with my own hotmail account and also with a test site on the same host usingActinic's latest SellerDeck 2013 and PC client, so it is not the customers specific hotmail account causing the problem. I suspect something has changed at hotmail, maybe to do with the outlook/hotmail/live merger etc.
I can send the same message from the same SMTP server at my web host via webmail or a pop3 client to the same hotmail accounts with no problem. So its not a problem with IP blacklisting etc.
So it seem hotmail suddenly doesn't now like the way the Actinic site's scripts put the email message together.
None of my Actinic settings have changed and customers not on hotmail are fine.
