# mail.example.com should be one of the results of a `dig +short mx example.com`
# Note that your provider might block all port 25.
# If STARTTLS header is missing or mangled, but https://starttls.info/ shows example.com as supporting STARTTLS,
# there might be a downgrade going on.

Python script to count occurrences of a field value in MySQL
#!/usr/bin/env python
#
# Using MySQL's grouping and counting features for very large tables is
# very slow. This Python script makes it much faster to count unique
# values of a given column. It selects the column values in reasonably-sized
# chunks (10k rows), and feeds those values into a collections.Counter.
#
# Assumptions: you have a .my.cnf set up to connect to the right DB with the
# right username and password. Your table has an id field, which is numeric and
# ideally autoincrement (for smooth distribution of values).
