Dunno.

If your problem is erectile dysfunction, then yes, apparently half the
planet shares your problem. Well, at least according to all the mail I
get.
Jeeez Andy! Not you too?? I think my <ahem> "problem" was my yahoo
account's fault. All those ads you mentioned. I left that account open
for a year or so to attract and soak in just about all the goobers and
their spam that exist in the entire world, and I just killed it off
yesterday. <cackles> Sweet.
I catch a ton of rubbish to an account I pretty much haven't used in
half a dozen years. And I have to admit, some of the subject lines are
funny as hell. There are between 200 and 500 in my junk folder every
morning; I still can't break the habit of scanning for false positives.
If you let your focal point slide to about 5 inches past your screen so
that things begin to blur just the tiniest bit, let your mind wander
(just the tiniest bit), it all begins to read like a surreal comic book.

I choked on my tea the first time I read that my new penis was waiting
for me.
... a riot.

Gmail makes me more "confident" you see.
Gmail.
You know, I think I'm learning that I think gmail really sucks. I've
never actually used web-based e-mail (and I've never really understood
why anybody who has an actual internet connection would in the first
place), so I don't really know what it's enticing feature(s) is/are. But
I sure can say that I get a ***t-load of spam from gmail accounts, and
that gmail either does not have an abuse mechanism in place, or simply
refuses to respond to it's use.
Bear in mind that the "from:" address is supplied by the user, and can be anything at all.

If you look carefully at the received: headers, you can tell whether it came via gmail's servers. Note that there typically will not be many hops between gmail's servers and yours, and probably you "know" them all.


Yeah, yeah, I on it. Before I spend the time writing a notice of abuse
mail I make sure of details like that. I only make that kind of effort
in special cases, and let filters handle the rest. It's been my
experience that mail sent to abuse@ generally gets *at*least* an
automated response of some kind. In my dealing with gmail I've never
heard a single peep, not from man nor beast, so to speak. An, of course,
no actions (that I could perceive, anyway) were ever taken. It's like
talking to a wall.

Whatever, I'll live. But I'm certainly not being presented with any opportunities to alter my
personal opinions about web-based email, or the providers or (with
exceptions, of course) users thereof.

Whatever the case, gmail is the new hotmail in my admin life. In fact,
aol has fallen to 4th place on my personal list of "The Rings of Hell".
gmail, hotmail, yahoo, aol, in that order.
more like .cn and .ko .ru, .es and .mx don't rate highly here either.

I hear you.

I regularly firewall off great gobs of China: if I see spam or ssh from anywhere in China, I block at least the entire /24 network entirely, from smpt and ssh.

For me that's a baby/bathwater thing. SSHD will take any amount of
activity from my own networks; everybody else gets 1 try at a successful
login and talks to the hand after that.

I take 5 ssh /hour from anywhere in the world, more from places in .au where I might visit.


Apparently the modern botnet shares the job of enumeration, so limiting one/IP address could, in principle, be overcome fairly quickly.

I do not expect email from those countries' networks I block. And I assume folk chop their networks into blocks: these /24 (or more) addresses are for adsl. Those adsl users have a fair chance of getting through, if they use the IAP's relay.

Of course, an IAP couldn't do this, and nor could a large organisation.

For mail, I let postfix and a content scanner deal with things. If the
connecting host can survive RBL and a reverse DNS lookup and wants to
send mail to an actual user in a domain I'm catching for, and the mail
isn't carrying anything that looks like cooties, then it's in the door
as far as I'm concerned. The receiving end can worry about whether it
was real mail or not.

Undo the blocks for while, and let them see what a good job you do:-)


Users whine about all the crap they get, but they REALLY whine when
critical mail doesn't reach them.


A rule I have is, block the source, but once it's received, deliver it. Target folder may be spam or windwoes if I think it's suss.

The only good email that's landed in my spam folder's from etrade. they write mail that fails any decent spam test - all-caps subject, talk about money ....
