just got my first mac on friday, i'm loving finding out how to do everything, but one thing has become extremely frustrating. i can't send my email! i have no trouble receiving it, and i've read everything i can get my hands on and all my settings seem to be correct. i've tried port 25, port 587, tried using smtp.mac.com, mail.mac.com, mail.optonline.net (my ISP) tried with SSL and without, everything i could change i've changed. my username and password and all account information must be correct since i'm able to receive mail, it's just the sending that's the problem. i'm using a dot mac email account if that makes any difference. one thing that concerns me is that under mail preferences, accounts, and account information, next to "outgoing mail server (SMTP)" it says "(offline)" next to the selected server. should this say offline? here is the exact message i'm getting, and no matter how i change it the message stays the same... cannot send message using the server (null) this message could not be delivered because your SMTP settings are not set. please use the account preferences panel to set the SMTP options for your account. select a different outgoing mail server from the list below or click try later to leave the message in yout outbox until it can be delivered. what am i doing wrong?
