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).

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).
