Given the recent rather rocky launch of MobileMe, it is no surprise that this week’s list of new and updated technotes from Apple contains a large number of support documents relating to MobileMe.

It is one thing to read the range of complaints in the MobileMe Apple Discussion Group . It’s another thing to get a sense of big problems from the horse’s mouth itself.

Apple’s new Support offerings for MobileMe are listed at the end of this post.

All MobileMe services get a look in, but there is a concentration on Sync issues and how to deal with them.

Some of the items are more useful than others. For example, I didn’t know what the maximum size of a MobileMe email message was until I read that “you can send and receive email messages up to 20 MB in size with your MobileMe Mail account.”

On the other hand, the technote on “How MobileMe filters spam messages” is less useful.

It tells you that

To minimize the impact of spam on MobileMe members, MobileMe employs several methods of detecting spam before it ever reaches your inbox. Spam prevention requires filtering mechanisms that include dynamic lists, trend analysis and content filtering.

However, it continues, “Filtering spam at the server is only part of the equation. You may find it helpful to use your mail application filtering to complement the server filtering.”

The only way to deal with false-positives is to contact MobileMe support:

If you feel that a friendly message was inadvertently deleted, you may want to ask your friend for a follow up email before you contact support, if you notice that multiple messages are being delayed, bounced, or not delivered, you should contact MobileMe Support directly.

Another cracker comes in the technote on viewing Mail.app’s Notes in MobileMe Mail:

Symptoms
If you create a Note with Mail in Mac OS X 10.5 Leopard, then view the note with MobileMe Mail, the text of the note will appear but the background color of the note will not be yellow.

Additionally, the notes cannot be edited in MobileMe Mail, and may appear to be from an “unspecified-domain” with no “To” address.

Products Affected
Mac OS X 10.5, MobileMe, MobileMe Mail

Resolution
This is expected behavior. For the best experience with Notes, use Mac OS X Mail only.

This document will be updated as more information becomes available.
