My suggestion is to use XML. PHP and Javascript has the Dom class that
supports this format very well. Its also easily extensible. And best of
all it's a text file.
Sample:
<mailbox name="some user">
<email>
<id>1234</id>
<subject>Send me the check<subject>
<to>nospam@nospam.com</to>
<from>someone@someone.com</from>
<message><![CDATA[blah blah blah blah blah
blah blah blah]]></message>
<attach>path to attach 1</attach>
<attach>path to attach 2</attach>
</email>
<email>
<id>5678</id>
<subject>Send me the check<subject>
<to>nospam@nospam.com</to>
<from>someone@someone.com</from>
<message><![cdata[blah blah blah ]]></message>
<attach>path to attach 1</attach>
<attach>path to attach 2</attach>
</email>
....etc...
</mailbox>
<mailbox name="some other user">
....
</mailbox>
