Hi. I hope you can help me, Grey. I am not exactly computer savvy. I have a related problem to the ones in this thread--at least I think I do. I'm on an "older" MacBook(with OS X Tiger) and have a (now called) MobileMe account for email. I use the mac.com addy.
I have been getting some kind of smtp message with some of my outgoing emails lately-this happens about once a year, sometimes on stuff I've forwarded from my work's email (not anything Mac), sometimes on stuff I have generated on my MacBook. I could not discern a pattern. Unfortunately, I never fully read the error message, but would click "continue" and most times, it would still send. I realized this wasn't the smartest thing I could be doing, so I mentioned to someone who said perhaps my email had been corrupted. Given that this is mac.com, I am doubtful. Then I remembered about the MobileMe stuff and came looking for help.
Thing is, I do NOT have both email thingies in my account--I only have mac.com. For all I know I got rid of me.com back when it first came out--but I am not one to fiddle with standard settings. (I'm only a few steps away from those who believe that hitting a button will blow the whole computer up....). This is long-winded, sorry. What I'm asking is this: do I just go into the me email settings and change over to XXXXX@me.com? Or should I wait until the stmp issue/error message comes up again, post it here for clarification before doing anything permanent? I understand the dual nature of the me/mac.com stuff and am fine with it, now that you explained it. I'm just not sure if doing that will solve this problem/ annoyance.
Also, I have never been able to access my email remotely (that is, when using any computer except my macbook). I know this is off topic, but any clue as to why (besides me being an idiot). Thanks.
