The SMTP components listed at
http://www.lemonadeformobiles.com/detail.html
These items are implemented already. But, their relationship to LEMONADE isn't in our docs:
SUBMIT
PIPELINING
SIZE
START-TLS
SMTPAUTH
These are sort of implemented:
8BITMIME - this is implemented, but off by default. 5.0 (or 4.8) could enable it by default, perhaps.
ENHANCEDSTATUSCODES - these aren't implemented by default, though they are configurable. Ideally, they'd be in the default configuration, and perhaps an ACL option would specify a status code. Version 5.0 might make an ACL invalid if it didn't specify an enhanced status code.
These aren't implemented at all, as far as I can see:
* BURL - this part allows integration with an IMAP server, a message is submitted with a an IMAP url to allow forward without download, etc.
* CHUNKING rfc3030 - allows large messages to be split into chunks.
* BINARYMIME rfc3030 - optimises bandwidth
* DSN - an SMTP extension defined in rfc3461 which allows the sender to specify conditions under which DSNs should be created.
Perhaps a starting point would be a wiki page - or a chapter in the documentation - explaining Exim's LEMONADE compliance.
