Our modem/router incorporates a firewall, which I had enabled, but,
from many years ago, back, when I believe the 80486 was the latest
whizzbang new CPU, I have been using a firewall/gateway computer for
our LAN - it may have been from before DSL, when we were on dialup. We
had started with an IPchains or IPtables (I am not sure which of those
two, came first) firewall, that was provided to us by a friend in a
local Linux User Group, and then, when I found Firestarter, we
conerted to that. But then, firestarter ran out of support, but, our
old firwall/gateway computer has been idling away, providing us with
its level of protection, with all of the other protections that we
have had, including the modem/router inbvuilt firewall.

In this application, with the MTA (?) that I am using; the gmail thing
has its own signature file, and I have just checked, and, in that, the
line with the hyphens, is not present, so I have inserted a blank line
into my signature stored in gmail, to see what effect that has. It
would not take effect in this message, but, in the next message that I
send, after this message.
