Just ideas.

Removing or deleting a single message from near the beginning of a large flat file takes an inordinate amount of time because the remainder of the flat file has to be rewritten all the way from the point of the deleted message to the end of the file and then truncated.

 Aren't you just adding bloat and complexity vs just storing the mail
 directly (maildir format) to a file on the drive? [...]

 You'll get better indexing and fast full text search by storing your
 emails in a database rather than a flat file, hopefully after decoding
 any attachments. Especially for spam scoring, analysis, and
 classification. Much better performance deleting or moving specific
 messages, too.

Do you have evidence to back up these claims, specifically re: mail
servers?

Like-for-like benchmarks, for instance?

Thanks,
