Syslog identifier should be something other than "Email"

[fangebee]

Hi, first let me thank you for this lifesaving project!
I've successfully deployed a headless server that allows old printers to continue functioning without trouble.

I've created a simple systemd unit file and it works fine too.

But, then, while trying to duplicate logs from journalctl to a dedicated plain log file in /var/log/emailproxy.log (we still love old stuff around here :) ) I struggled to craft the correct rsyslog configuration.

I was hoping I could use the following simple /etc/rsyslog.d/emailproxy.conf configuration file:

:programname, isequal, "emailproxy" -/var/log/emailproxy.log
& stop

But not luck :(
Looks like rsyslog considers that the programname is "Email" because every log line starts with "Email OAuth 2.0 Proxy: ...". Therefore, the following configuration works:

:programname, isequal, "Email" -/var/log/emailproxy.log
& stop

It works, but it's not really satisfactory.

Maybe I'm doing something wrong, but for now I've patched the code to make sure the first word is "emailproxy".
