The smtplib module automatically uses CRAM-MD5 for authentication if
it is available.  If you wanted to use some other hashing scheme then
I guess you would have to implement it yourself by overriding
SMTP.login, or find another SMTP module that already supports it.

The above comment about security is bad advice.  Security is all about
layers.  Just because the data stream is already encrypted (read:
decryptable) does not mean that password digests are a waste of time.
In fact, the two techniques are usually considered complementary:  the
encryption process protects your application data, while the password
hashing protects your authentication details.
