RE: Port 113 requests?

Quoting "Slighter, Tim" <tslighter () itc nrcs usda gov>:

you really should try and specify that the rule "drops" instead of
reject so
that the potential intruder is not provided with any information about
their
attempted connection.

In this case (SMTP AUTH), if you drop instead of reject, you will have to wait
for the remote server to time out its auth connection before it lets you get on
with SMTP.  This can slow mail delivery down substantially.

cheers:
andy
