Unless a blacklist adds victims by AS number, a change of MTA's IP
(hence the hosting) and an appropriate DNS reconfiguration is
sufficient to sidestep it.
Of course, one can get an already blacklisted IP, so a certain amount of
"hope and pray" applies here.

Landlines still have their use here. They are shrinking to business and
government communications, sure. But it's curious how many people still
rely on that "you leave your job at office" principle.

That's something I agree with. Still, I propose to wait until
post-Generation Z gets their first job.

The trend is here, sure, as long as you consider small business.
Large one - not so much.

I saw no unsolvable problems in doing it so far, hence my interest to
your statements. And yes, I do not consider myself an expert in all
things related to SNMP, MTAs and the like.

And cause different issues, because you're no longer on an IP with an 
established history. You're also assuming that they're blocking by IP 
rather than domain, which is quite bold assumption since the blacklist 
is a black box and domain based blacklists most certainly exist. That 
said, I have in the past configured specific domains to recieve email 
from specific IPs because they arbitrarily stopped accepting mail from 
other IPs.

Or, you're trying to send to someone who's blacklisting broad ranges of 
IPs or ASs and you're just wasting your time changing IPs. Nothing like 
find that out after going down that road.

Why? Current young working age people are alredy far less invested in 
email than their older peers. This isn't changing as they continue to 
work. If anything, they're pushing companies away from using email as a 
primary means of internal communication.

Maybe not ten years ago, but CIOs need to now have a good answer to why 
*not* outsource email. For the most part, large businesses that aren't 
IT providers don't particularly want to manage email servers. It might 
be hard for them to change their existing infrastructure, but in my 
experience it's something they're definitely looking at.

I never said the problems were unsolvable. (For the most part. I have 
seen horror stories where the best solution was to abandon a domain.) I 
do propose that the effort involved is so large that for most people it 
isn't worth it. As the number of people who care to try continues to 
shrink, the motivation for the large providers to bother worrying about 
small providers shrinks even faster. At some point the percentage of 
non-spam email originating from providers with less than a million users 
will be so small that the benefits in just cutting it off will outweigh 
the cost of doing so. We're already well past the point where sending 
from a gmail account is an accepted diagnostic step--which makes it hard 
to explain to an ordinary person why it wouldn't be the default.

A blank slate. There's nothing wrong with it. Blacklists are called that
for a reason, they do not block whole IPv4/IPv6 address space.

Haven't encountered one yet, but I trust you on this.

And that's where "hosting" comes into play. Blacklisting, say, whole
Amazon AS is a little extreme, don't you think?

I disagree. "We do things this way because we got used to it" still
holds some weight.

But they lack weight to do so effectively yet. Certain positions come
with an age.

Privacy of internal communications? Risk limiting? A good CIO should
always have pro- and contra- arguments for any proposition.

I'll believe it then I'll see it.

Except that other anti-spam algorithms take into account how long a 
domain has been around, and how long a specific IP has been in use for 
that domain. (In order to try to counteract spammers doing exactly what 
you're recommending in order to avoid IP based blocklists.)

>Blacklists are called that
>for a reason, they do not block whole IPv4/IPv6 address space.

Sure they do. Even in this thread you've heard people advocate blocking 
entire countries. You seem to be arguing based on some particular 
blacklist implementation without recognizing that other recipients use 
other blacklists, some of which may even have policies that you might 
think are idiotic. If you're trying to send an email to someone whose 
provider implements idiotic policies, your assessment of their policies 
is basically irrelevant. (Though it may eventually encourage you to 
simply stop caring about whether the email gets delivered.)

See above. Also, there are certainly recipients who are more skeptical 
of amazon IPs exactly because they're so easy to spin up. Also, amazon 
themselves will ask questions if you start hopping IPs and asking for 
PTRs on each of them for email delivery.

Again, each of these things is usually surmountable, but rational people 
eventually have to ask whether it's worth the effort vs throwing in the 
towel and outsourcing to a first tier provider.

Normally, change of IPs occurs every time you find a better ISP.

Widely used domains usually adopt policies which grant decent
deliverability.  Hotmail users are obviously happy having every new
contact's message delivered in their spam folder.  I prefer a spam
folder not having to be rummaged through —SA score ≥ 9.

These lists are used for content inspection.  If a message contains a
link to a bad web site, presumably inviting recipient to click on it,
it is worth blocking it.  That's a somewhat poor technique.  M$
rewrites links so as to redirect them to a local proxy.  Another
approach is to use DNS RPZ.

It is true that many people turn to Gmail and similar services.  The
reasons why they do so are certainly complex, but I don't think
getting out of blacklists holds a relevant position in the overall
statistic.  I, for one, never had this problem after 20+ years of
running my own mail site.

So you didn't look for what RHSBL means? The level of "my experience

The existence of an Internet swamped with spam has led to spam fighters
policing it and users demanding a means not to receive it. Between the
two, sending email directly has become more and more difficult. Spam
hasn't disappeared or been reduced, but the spam fighters have impacted
on the basic concept of email communication and are achieving what the
spammers haven't achieved - making email communication fraught and
unreliable.

An eye opener for me was when my site got blacklisted as a spammer because
I was sending bounce messages for every email I refused to accept (due to
spam).

False positives happen more often then you'd think when you're receiving
legitimate emails in English, from international non-native speakers,
discussing legitimate wire-transfers (because when you send your kid to
another country for school, you might want to send them money). I still
think that it's super important to know when your email gets dropped on the
floor.

The potential fallacy here is that spam may not have been reduced from
its levels of previous years, but the real question is whether it is
less than it would be *today* without the efforts of the spam fighters.

It is your job to demonstrate that the spam fighters have had a
significant impact on the flow of spam over the internet. My
contention is that they will have simply brought the use of mail
to the point of uselessness if their ideas gain a significant
amount of traction.

I would be. Every day I read an email from my server listing every
sender's email address where my server has refused to accept the mail
and which were sent to one of the three real names my server deals
with. 

It's not a big task, as the overwhelmingly vast majority of refused spam
is sent to obviously made-up names on my domains in the hope of getting
a bounce to the spoofed From: address.

Fifteen or so years ago, out of curiosity, I said to hell with fake
email addresses, I'd go on using the Net with a real address (the one
in the headers has been my main address all those years) and see if I
could deal with the consequences. I've had to give up one of my main
weapons, the DNS check, as so many small businesses now outsource to
some other small business which doesn't really understand email. Also,
a lot of domestic ISPs now give their users PTR records. I've
compromised by routing the PTR-less stuff straight to a spam folder.
and glancing at it occasionally. 

It has worked out pretty well, I don't see a lot of spam, because I
refuse all the NDR stuff, and don't have a backup mail server. Much of
what I do see is 'real' spam, bloody idiots in my own country who
genuinely believe that the way to sell me stuff is to send me
unsolicited email. Repeatedly. 

I keep my own blacklist, and the mailing companies and tiny ISPs who
provide services to these spammers go into it. I used to complain a lot
to abuse addresses, but it never helped, and the big people don't even
have abuse addresses now.

So, is that from your own email server or from an ISP -- if from an ISP, which 
ISP?

My own server, I'm afraid. I can't imagine any ISP offering a service
like that, it requires a valid account list, and the only way to
achieve that through an ISP is to have named mailboxes there.
