ooooook I understand now :) I was thinking that the client could send
plaintext and i could have the password encrypted in the database. The
reason I was trying this to begin with was a little script I wrote to
convert a passwd/shadow file into dbmail users for a server conversion
so I wouldn't have to know the user's passwords. I guess I'll need to
know these passwords because I'm not willing to brute force the md5
shadow salts.
Thanks!

Quoting Aaron Stone <[EMAIL PROTECTED]>:
Ah, right - ok, so either you need plaintext in DBMail and Sendmail will
retrieve the raw password and hash it as necessary in order to compare
it with the hashes received from the client, or you need to restrict
Sendmail down to a single hash mechanism that matched exactly with the
hashed passwords in DBMail. Remember that password hashed are one-way --
if the database contains a hash, and the client sends some other hash,
there's no way to convert between them in order to authenticate.
