Depends on what you need it for,

Whith what I use, it is still easy to see those details. The blocked
sites are still logged and the yet unblocked ones as well.

And that blocking is just what this thing does. You can also use it to
block SMTP traffic where the logins and passwords are not correct after
X amount of times.
Obviously all other SMTP access without passwords is blocked by default.

I did. I removed all your text. Retaining it was unnecessary and
irrelevant, as I was suggesting an alternative.

Yes, but the hold time is arbitrary. One could, for example, use 900.

I'll ignore the former, since I am already doing so, and be mindful of
the latter.

I understand that. Still seems a odd way of doing things and a more
apropriate time would be 43200 or 86400 (12 or 24 hours)
Strange that they went for such a short period.

I was waiting for this. :-D
I first wanted to elaborate how I was specificaly not talking that kind
of trafic and then I thought, sod it, people will understand I was
talking about users getting access to ESMTP servers and not the mail
delivery in itself.
