MobileMe SMTP problems
At least some MobileMe subscribers have been experiencing problems with Apple's SMTP servers, according to forum discussion. In attempting to send out e-mails, the subscribers have been running into timeouts, at which point they have been prompted to pick another SMTP server. The consequence has been inconsistent delivery, frequently blocked but sometimes successful.
The issue is said to occur regardless of the ISP used, and some error messages have explicitly identified the rejection point as on Apple's end. Delivery failures have in a few cases been occurring for months. Apple has yet to provide a solution for the problem; some users have suggested the temporary solution of using smtp.mac.com as an outgoing server, but this may not provide any results.
