[New-bugs-announce] [issue32803] smtplib: LMTP broken in the case of multiple RCPT

[jasen betts]

New submission from jasen betts <jasen.betts at gmail.com>:

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
