BUG: lazy logging incompatible with MultiEmailHandler?

[rderooy]

Describe the bug
An issue I have with the MultiEmailHandler is that my log messages are written to be compliant with lazy logging (pylint warning W1201).

This works fine with the other loggers I use, but breaks with RedMail MultiEmailHandler, where my messages are full of '%s' where variables need to be.

e.g. this breaks RedMail and remains as "%s":

LOG.info("message %s", variable)

But this works:

LOG.info("message " + variable)

To Reproduce
Steps to reproduce the behavior:

1. Use lazy logging function
2. observe email, the %s will not be substituted for the variable

Expected behavior
%s to be substituted for the variable, like with other logging functions. Or at least some explanation in the docs about this.

Screenshots

Email provider:

• Email service: private
• Application to view the email: not relevant

Environment (please complete the following information if relevant):
