Simple Mail Access Protocol
The Simple Mail Access Protocol (SMAP) is an application layer Internet protocol for accessing e-mail stored on a server. It was introduced as part of the Courier suite, with the goal of creating a simpler and more capable alternative to IMAP.
Notable features of SMAP:
- MIME attachments can be transmitted in their raw, decoded form. This allows large base64-encoded attachments to be transmitted without the 4:3 inflation that base64 encoding usually incurs.
- Support for sending outgoing e-mails through the SMAP connection, instead of using a separate SMTP connection to the server. An outgoing message only needs to be transmitted once to send it, and save a copy to a server-side folder.
- Unicode folder names, with native support for hierarchy.
- SMAP clients and servers can fall back to IMAP if the peer does not support SMAP.
