Cool Fire 27526e431b Changes static logfile string to variable 
Since we don't want to re-declare a log file name we already
have a varialbe for, use the existing variable to set dovecot_log.

Update lighttpd-auth.conf 
I have lighttpd 1.4.45 (Debian 9) and auth error log is different.
Now printing mod_auth and not http_auth.
I think that the change was in Lighttp 1.4.42

Avoid injection using quotes after `auth` command; 
Added non-greedy fallback for quoted something (with lookahead simulated possessive greedy catch of non-quoted parts `[^"]*(?=")`).
Note that because host-info's are hereafter (with foreign input in-between), we would not use greedy or non-greedy catch-alls (`.*` or `.*?`) here (preventing performance losses).

Serg G. Brester f59df2e156
Avoid any injecting on protocol (e. g. tries using camel-case) 
The phrase "AUTH command used when not advertised" is precise enough as anchor here, so prevent by any foreign-input (any auth protocol error).

Exim failregex: Include lower/mixed case AUTH 
When reporting the error `AUTH command used when not advertised`, Exim
starts with `SMTP protocol error in "........."`. Here, Exim logs the
SMTP command as it was provided by the connecting client.
https://github.com/Exim/exim/blob/exim-4_89+fixes/src/src/smtp_in.c#L2850

According to RFC 5321 (SMTP) "[..] a command verb [..] MAY be encoded
in upper case, lower case, or any mixture of upper and lower case with
no impact on its meaning."
https://tools.ietf.org/html/rfc5321#section-2.4

Lower case `auth login` brute-force attempts were seen in the wild and
were not caught by the current failregex.

This commit makes the failregex case-insensitive for the `AUTH`
command, so that lower case (`auth`) or mixed case (`aUtH`) now also
match. The failregex was already case-insensitive for the command
arguments (e.g. `AUTH login` already matched).
