Hotmail generated email undeliverable using squirrelmail
I use squirrelmail (1.4.22)to send and recieve email from my inmotion hosting web address. Recently I have been told by several people that when they send an email to me they recieve a message that it was not deliverable. I believe, but am not certain, that this has only occured from people sending mail from Hotmail accounts. Any thoughts? Many thanks!
