Great.  But a fresh date oddity, expired before publication :-)

Some observations minus the few simple nits reported by IDnits:

s/are therefore often decide/therefore often decide/ (to accept)
or maybe "are therefore often forced to accept". 

Status codes 0..5:  Intuitively I'd expect "0" to be "okay".

Digest = MD5( secret ":" mailbox ) could attract the attention
of security folks, how about using HMAC(x, y) instead of MD5 ?

Anonymous mode, is that MD5( ":" mailbox ) or MD5( mailbox ) ?

Security:  The secret is defined to be 1*50(VCHAR), maybe say
at least 16 VCHARs instead of 128 bits.  MD5 could handle bit
strings if you'd want this, but you want ordinary VCHAR bytes.
