PyMailGUI user configuration settings.
Email scripts get their server names and other email config options from
this module: change me to reflect your machine names, sig, and preferences.
This module also specifies some widget style preferences applied to the GUI,
as well as message Unicode encoding policy and more in version 3.0.  See
also: local textConfig.py, for customizing PyEdit pop-ups made by PyMailGUI.
Warning: PyMailGUI won't run without most variables here: make a backup copy!
Caveat: somewhere along the way this started using mixed case inconsistently...;
TBD: we could get some user settings from the command line too, and a configure
dialog GUI would be better, but this common module file suffices for now.

# which can handle Unicode encodings more accurately on a message-level basis;

# in all cases, falls back on UTF-8 if your encoding setting or input does not
# work for the text being sent (e.g., ascii chosen for reply to non-ascii text,
# or non-ascii attachments); the email package is pickier than Python about
# names: latin-1 is known (uses qp MIME), but latin1 isn't (uses base64 MIME);

# non-ASCII headers, as well as non-ASCII names in email addresses in headers,
# in composed messages when they are sent;  None means use the UTF-8 default,

# is assigned to None (or 0), loads will have no such limit; use this if you

# makes full loads too slow to be practical; PyMailGUI also loads only
# newly-arrived headers, but this setting is independent of that feature;

# with all original mail recipients, after removing duplicates and the new sender;
# if False, no CC prefill occurs, and the reply is configured to reply to the
# original sender only; the Cc line may always be edited later, in either case.
