hi again,

but, why is "imapd -s is for IMAP connections that are externally wrapped
by SSL" --> considered "BAD"?

Because TLS allows one to select which certificate to present, and SSL doesn't.

aha.

SSLv2 should not be used at all if you can help it

gone.

i presume, then, that SSLvX *starts* encrypted ... hence the port 993. true?
Yes.

it's actually starting to make sense =)

Actually, ALL:!aNULL:!NULL:!EXPORT:!DES:!LOW:@STRENGTH is even better; I did some extra reading.

   tls_cipher_list: TLSv1:SSLv3:!NULL:!EXPORT:!DES:!LOW:@STRENGTH

i _thought_ the !ADH is there by default ... and i see no reason NOT to
explicitly include (ALL) the high/med grade ciphers.

It is not. TLSv1 will include it... so you need either !ADH or !aNULL (the later is better). Try openssl ciphers -v, and you'll see.

got it. cryptic, but with a little staring ... clear.

thx!  it's working perfectly now ... on to the next step.

best,

richard
