SMTP
- SMTP(host='', port=0, local_hostname=None, [timeout, ]source_address=None)
This class manages a connection to an SMTP or ESMTP server.
SMTP Objects:
SMTP objects have the following attributes:
helo_resp
This is the message given by the server in response to the
most recent HELO command.
ehlo_resp
This is the message given by the server in response to the
most recent EHLO command. This is usually multiline.
does_esmtp
This is a True value _after you do an EHLO command_, if the
server supports ESMTP.
esmtp_features
This is a dictionary, which, if the server supports ESMTP,
will _after you do an EHLO command_, contain the names of the
SMTP service extensions this server supports, and their
parameters (if any).
Note, all extension names are mapped to lower case in the
dictionary.
See each method's docstrings for details. In general, there is a
method of the same name to perform each SMTP command. There is also a
method called 'sendmail' that will do an entire mail transaction.© Python Software Foundation. PSF License Version 2 · Official docs ↗
