Hi I'm having problems sending mail through my dot mac account. i always get the following message: "This message could not be delivered and will remain in your Outbox until it can be delivered. The SMTP server "smtp.mac.com" doesn't support authentication. Please check your account settings and try again." I've had a lot of troubles with authentication and CERTIFICATES lately. A lot of times Safari wont connect to the internet in a public place like McDonalds and it says something about an invalid certificate. Its weird though, cause if i've connected in some other place used safari and left a window open, then if i go to McDonalds it connects fine no problems. Weird huh? If anyone knows what im on about please help. Thanks.
