bulkmail.py

#!/usr/bin/env python3

#....ported to python3 02/2020
# ....bulkmail.py: send bulk email to recipients in RecListFileName
# ....Werner Joss, 2017,2018,2020
# ....License: GPL
# ....Message is from MsgFileName, preceeded by 'Hallo <Name>,\n'
# ....RecListFileName must contain one Recipient per line in the form 'Vorname Name <email>'	note: surrounding <> for email Adress is required !
# ....Default Subject may be overridden in MsgFile (line starting with 'Subject:'
# ....this can send messages with utf-8 encoding, not just ascii (as bulkmail_asc.py) 30.04.17
# ....add max No of Msgs sent per run (SPAM Protection) 10.03.18
# ....guess gender :) - see https://pypi.python.org/pypi/gender-detector 10.03.18 - replaced by gender_guesser: https://pypi.org/project/gender-guesser/ 02/2020
# ....getopt Argument Parser 11.03.18
# ....add Attach File Option 11.03.18
# ....fix some bugs 18.03.18
