Already using one of the popular AUTH patches? acceptutils is different.
Compare and contrast, noting that:

- TLS is included
- Message submission has been redesigned to cohere
- Submission and incoming SMTP are distinct services
- Neither of them runs weird privileged child processes
- POP3 has been improved, too
- These improvements come from new programs, not patches
