NLnet M1 Progress - markov2/perl5-Mail-Box GitHub Wiki
This is the result of RFC-Editor Search for the keyword MIME, which produces 198 results (jan 2025). The previous full RFC check (also supported by NLnet) took place in 2003, so older RFCs are not re-investigated. Besides, some other crucial RFCs were selected by hand.
