Despite it being neat software, I'm finding it near impossible to run 
mlmmj mailing lists because mail is being treated as junk by big mail 
outfits such as hotmail and btinternet.

My own mail server (which includes rspamd) accepts mlmmj mailing list 
mail without a problem. And I can observe that my mail, as received, is 
checked to be valid for DKIM, SPF and DMARC. I've also checked some mail 
against e.g. mail-tester.com and not found any problems.

My mail server is not blacklisted anywhere.

Despite this, a number of recipients seem to have messages routinely put 
in junk, and they don't all monitor junk. This creates a big problem, 
and makes a mailing list unusable.

Obviously, I have no influence with hotmail, btinternet, etc who 
probably wouldn't even reply to me.

It seems that big commercial outfits want to force people into paid 
services and to prevent them using simple but valuable mechanisms such 
as an ordinary mailing list.

Is there anything I can do to deal with this problem?

SPF does not go along too well with traditional mailing lists:
(thats why more and more mailing lists rewrite the From:)

$ dig +short black-sheep-research.com mx
100 mx.yorkshiremail.com.

$ dig +short black-sheep-research.com txt
"v=spf1 include:yorkshiremail.com ~all"

$ dig +short yorkshiremail.com mx
100 mx.yorkshiremail.com.

$ dig +short mx.yorkshiremail.com
164.90.179.118

$ dig +short yorkshiremail.com txt
"v=spf1 a ip4:79.79.41.36 ip4:164.90.179.118 include:spf.smtp2go.com include:servers.mcsv.net ?all"

... but I get your mail, via the mlmmj list from this IP:

Received: from adhara.zumppe.net (adhara.zumppe.net [198.101.246.47])

This is why my rspamd gives your mail 3 spammy points:

R_DKIM_REJECT(1.00)[smtpcorp.com:s=a1-4,black-sheep-research.com:s=s151337];
DMARC_POLICY_REJECT(2.00)[black-sheep-research.com : No valid SPF,reject];

below just included for completeness, no score assigned:

DKIM_TRACE(0.00)[smtpcorp.com:-,black-sheep-research.com:-];
FROM_NEQ_ENVFROM(0.00)[martin@black-sheep-research.com,mlmmj@mlmmj.org]

I have no idea whether mlmmj has an option to rewrite the "From:"!
(And I hate the rewritten "From:"s...)

Thanks. I don't understand why your rspamd says black-sheep-research.com 
has no valid SPF.

Your "digs" show that it has an include for yorkshiremail.com, which in 
turn specifies both my own mail server (mx.yorkshiremail.com) and 
smpt2go.com which is the mail relay that I use for general mail sending.

Where is there an SPF problem?

I don't either understand why your rspamd doesn't like the DKIM 
signature added by the mail relay (smtp2go.com) if that is what it is 
complaining about.

Because the IP of the sending server (mlmmj list server at
198.101.246.47) is not in the SPF-published "allowed sender" IP list:

$ echo black-sheep-research.com | smtpctl spf walk
79.79.41.36
164.90.179.118
45.55.101.18
205.201.128.0/20
198.2.128.0/18
148.105.8.0/21
207.58.142.208/29
207.58.147.64/28
216.22.15.224/27
43.228.184.0/22
103.47.204.0/22
103.36.108.0/22
103.2.140.0/22
203.31.36.0/22
66.128.144.88/29
198.74.56.28

(smtpctl ist a tool on OpenBSD)

OK, thanks. I guess that's inherent in mail server usage.

But I'm having problems with btinternet and hotmail users receiving from 
my mailing lists even when I am the sender. And in the case where I am 
the sender, the list server is my mail server, and so the mail should 
arrive with correct SPF, DKIM and DMARC.

Yet it is still treated as spam.

Is there any solution to any of these problems? Or are conventional 
mailing lists obsolete, to the detriment of the usefulness of email?
