Without this reset, starttls would fail if a connect/starttls was done after a
quit, because smtplib assumed the existing value of emspt_features was
accurate, but it gets reset when starttls completes (and the new value does
not contain the starttls capability, since tls is already started at that
point). (There may be additional places where this lack of reset was an
issue as well.)
Patch by Milan Oberkirch.
Normally an SMTP server will return an error, and smtplib will then issue an
RSET to return the connection to the known starting state. Some servers,
however, disconnect after issuing certain errors. When we issue the RSET,
this would result in raising an SMTPServerDisconnected error, *instead* of
returning the error code the user of the library was expecting. This fix
makes the internal RSET calls ignore the disconnection so that the error code
is returned. The user of the library will then get the SMTPServerDisconnected
error the next time they try to talk to the server.

requires them. Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface. Fixed
shebang lines in the unittestgui and checkpip scripts.

This is a partial fix to the issue of servers disconnecting unexpectedly; in
this case the 421 says they are disconnecting, so we close the socket and
return the 421 in the appropriate error context.

tests by me.

As far as I can tell, the try/except was ancient code, from before the email
package rewrite where the philosophy of never throwing parsing errors was
adopted.
The RFC doesn't say that they are allowed; apparently many mailers accept
them, but not postfix. Contributions to this patch were made by Felipe Cruz
and Catalin Iacob.
The changeset also adds additional indirect tests for quoteaddr (null address
and IDNA-encoded address).
by the server. Many servers are buggy and advertise authentication methods they
o not support in reality. This change makes smtplib.auth() work more often in
the real world, where we face misconfigured servers and servers that advertise
methods they don't support due to the madness that is SASL.
