mail recipient gets phishing warning from Mail on MacBook Pro but not iPod
I have a friend I'm corresponding with - he tells me that every one of my emails comes into his PC with a Phishing warning. But get this: last night I responded to an email from him on my iPod, and he said there was no warning.
I am running Sophos Anti-Virus on my MacBook Pro (scanned and updated regularly), using the same gmail account synced on the MacBook and the iPod, and not using MobileMe. Any ideas?
Thanks!
MacBook Pro, Mac OS X (10.6.7)
