class smtplib.LMTP(host='', port=2003, local_hostname=None)[source]

LMTP - Local Mail Transfer Protocol

The LMTP protocol, which is very similar to ESMTP, is heavily based on the standard SMTP client. It’s common to use Unix sockets for LMTP, so our connect() method must support that as well as a regular host:port server. local_hostname has the same meaning as it does in the SMTP class. To specify a Unix socket, you must use an absolute path as the host, starting with a ‘/’.

Authentication is supported, using the regular SMTP mechanism. When using a Unix socket, LMTP generally don’t support or require any authentication, but your mileage might vary.
