Not going to argue against outsourcing, that can be a good call, but in
case it helps you buy time to evaluate the options:

DKIM doesn't touch the envelope, only the message headers.

I've found that what works the best is "REMOVE_DKIM_HEADERS" set to 3,
BUT editing Handlers/CleanseDKIM.py to not rename the
authentication-results header, which is needed for ARC validation.  Let
it rename the others out of the way but not that header.

Set DEFAULT_DMARC_NONE_MODERATION_ACTION to Yes, so that the sender's
domain owner doesn't get deliverability reports from sites with folks
subscribed to the list; DMARC reports are otherwise a major privacy
problem.

Then the MTA for the domain needs to sign outbound mail.  If doing ARC,
you're also going to need to record the decision to ARC-sign, which I do
by having the MTA shove that into a header when feeding into Mailman,
then remove that header from the messages out from Mailman.

Given all the steps I put into

it's hard to argue against outsourcing.  Ugh.  Some days I truly hate
email.

Life is too short to go visiting a hundred random web sites to see if
there is anything interesting on them. I know about RSS, but most of
the web forums don't, and RSS with passwords is flaky at best.

Returning to mailing lists, Sympa is sort of the European equivalent
of Mailman. It's written in perl rather than python, works well and
has built in DKIM and ARC support that actually works. I wrote the ARC
support.

I've also been happy with groups.io.  Their free level is pretty good.

That's a bait and switch to me.

Web (only) forums do *NOT* offer the same functionality as mailing lists.

Perhaps some forums can email posts to members (subscribers).

Maybe even some of the forums allow new submissions via email.  I don't 
know.


Note how that's three distinctly different classes of forum applications.

Honestly, I see mailing lists as a dying breed (said as I post this to a 
mailing list).


That's your opinion.  One I happen to moderately disagree with.


A forum tends to work out better.


That's also your opinion.  One I VEHEMENTLY disagree with.

As someone who subscribes to, reads, and interacts with about 300 
mailing lists and 200 newsgroups, there is no way in REDACTED that I'm 
going to go to 500 different forums, many of which behave differently.


For me, all 500 different lists / newsgroups come to /one/ interface 
where I have /complete/ control over.


Just because that an airplane and hiking shoes can get you across the 
country, does not mean that they are even remotely comparable to each other.


It's a pull (users pull content only if they want to receive the 
content) rather than a push (users are pushed content - if they are 
subscribed - whether they want to or not).


Pulling from 500 different locations as opposed to 500 different 
locations pushing to my single location is a COMPLETELY different usage 
model.


Baiting me with a push and then switching to a pull model is 
disingenuous at best.


Don't even get me started on the UI/UX of things that I don't control.

Certainly understand wanting to get away from running your own thing,
but if you're open to considering an alternative bit of software that
cares a good bit about making sure to not break DKIM, et al, you might
check out pglister which is what postgresql.org uses and which we
maintain.  We're not a huge operation but not small either (few
hundred thousand emails a day outbound).

Might be a few rough spots around getting it to work outside of our
infra, but that was part of the original design and hopefully wouldn't
take too much and we'd appreciate it being more accessible to others to
use (and contribute back to).

Re: [mailop] Current OSS anti-spam software best practice?

[Michael Peddemors via mailop]

In general, outbound rate limiting is the most important, but as to 
outbound scanning, it really depends on your size.


A smaller email system, might be able to depend strictly on outbound 
rate limiters, but larger ones need outbound scanning as well, because 
of piggyback spammers... the ones where the hacker only trickles out 
spam on top of a legitimate email account, to keep volumes low enough to 
be under the radar, but if you have 50 or 100 of those, you will get in 
trouble.


Of course, virus scanning outbound is a must, and you can start with 
outbound scanning but at a 'higher score' than inbound, to at least 
identify worst cases.


But once you get to a large size, it does become your responsibility to 
be a better netizen, and watch egress traffic more closely..  not that 
that happens in the real world often I am afraid, there are some well 
known 'too big to block' that seem to put emphasis on inbound, not 
outbound, often for purely commercial reasons..


And one thing you didn't mention, how is your use of RBL's?  You should 
of course use good and sane RBL's BEFORE you pass it on to SA for 
scanning, as well as other best practices at the SMTP layer, if only to 
reduce loads on your servers.  SpamRats, SpamCop, Spamhaus etc..


Once you have done all that, you will find that your filters, whether 
SpamAssassin, or other types, should be only catching levels of around 
5% of the remaining volumes that reach that point..


You also might investigate custom SA Rule repositories, as the whole 
world isn't the same ;)

Hi all,

I'm wondering which software is currently the best practice in OSS

We are still using Spam Assassin on our main setup, but I feel that it's 
not aggressive enough to cope with current spam patterns, especially 
with regards to its rather conservative bayesian learning parameters.


Is it generally being superseded by other OSS solutions, or should I be 
looking into fine-tuning it? It's a shared cluster, so per-mailbox 
bayesian learning is an important feature for us.


Is it generally best practice to also scan all outgoing e-mail on a 
shared e-mail cluster for spamminess?

Another +1 for rspamd. It is pretty good even with close-to-default
configuration.

It is definitely helpful to pass outgoing mail through the same system
in order that it can watch message-ids and reduce score for replies to
locally originated mail. It's also a good place in the pipeline to sign
dkim if needed.

Whether to have it score outgoing mail for spaminess really depends on
local policies. Even if it's not blocking anything it maybe useful to
have it as an alerting mechanism to pick up on potentially dubious
accounts.

FWIW, I’ve been quite happy with a setup that has OpenBSD spamd(8) doing 
greylisting and tarpitting based on locally generated and imported greytrapped 
blacklists, feeding on to the actual mail server(s) that do their content and 
header filtering using Spamassassin or what the local admins prefer.

My now probably ripe for refresh writeup can be found at

 (with 
other field notes to be found nearby)

All the best,

If you're going to prevent some part of the mail stream from leaving your
infrastructure, then possibly, but IMHO marking something as spam and
still sending it on is adding insult to injury from the recipient's
perspective.

[mailop] Current OSS anti-spam software best practice?

[Dr. Christopher Kunz via mailop]

Hi all,

I'm wondering which software is currently the best practice in OSS 
(incoming) spam detection and filtering?


We are still using Spam Assassin on our main setup, but I feel that it's 
not aggressive enough to cope with current spam patterns, especially 
with regards to its rather conservative bayesian learning parameters.


Is it generally being superseded by other OSS solutions, or should I be 
looking into fine-tuning it? It's a shared cluster, so per-mailbox 
bayesian learning is an important feature for us.


Is it generally best practice to also scan all outgoing e-mail on a 
shared e-mail cluster for spamminess?


Best regards,

--ck
