Portal "Alert Me" and incoming e-mail customization

[OK]

We have incoming e-mail configured for our libraries.
But there are some other requirements:

1. Improving "Alert Me" feature
2. Improving incoming e-mail settings (writing data to sub-folder structure)

1. Document publication via email confirmation

Scenario:

a) SharePoint Doc Lib is configured with incoming
email address for publication and "Alert Me" is set up for users who need to
be notified.
b) Document is sent to this email
c) SharePoint responds with email confirming that document has been
published (with link) or reporting error of publication - but only for this
particular user, not to receive mesages if someone added or changed anything

2. Publication to concrete subfolder (in Document Lib)
For simple case - root folder or its direct (1st level) subfolder everything
works fine.
But we need to be able to publish documents in more sophisticated path -
e.g. \Folder_Root\Folder1\Folder2\......

You should use SharePoint object model to do the customization like that

For the Alert me you could tie in to the ItemAdded event to build and
send your email

You can also use the IAlertNotifier to modify the OOTB email alerts

If you don't want to do this in code there are several commercial
products that do this such (blatant plug, one is my own)
