smtplib's LMTP support is broken, 

 LMTP returns multiple responses at and of data if there have been multiple successful RCPT TO  commands, but smtplib::data() only looks for a single response.

see the example conversation on page 3 of RFC2033

This makes LMTP unusable if there is more than one RCPT

3.5 and 3.4 are in security fix only mode, so narrowing the relevant versions.
