No option 'postmap_command' in section: 'postfix'
The documentation <https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.html> says that I need to create /path/to/postfix-mailman.cfg containing: [postfix] transport_file_type: regex
Then append the path to the [mta] section of mailman.cfg, viz:
[mta]incoming: mailman.mta.postfix.LMTPoutgoing: mailman.mta.deliver.deliverlmtp_host: mail.example.comlmtp_port: 8024smtp_host: mail.example.comsmtp_port: 25configuration: /path/to/postfix-mailman.cfg
That is exactly what I have done on my test platform, but I get the error below when creating a list. Perhaps I overlooked something?

This is a bug. Whether it is a bug in documention or code is not completely clear.

So, if I understand this correctly, there is no need for the addition of this parameter: ``` configuration: /path/to/postfix-mailman.cfg ``` to the mta config block in mailman.cfg in a non-docker environment, or when only using hash tables?? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-)

Correct.

Great.
So, since the creation of that file is prominent in the doco, maybe a note can be added to that effect?
Thank you.

I'm looking at https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.ht... and my thought is at the paragraph
Regular Expression tables remove the additional dependency of having postmap command available to Mailman. If you want to use regexp or Regular Expression tables, then add the following to Postfix’s main.cf file:
add another section header
Regular Expression Tables
and change that text to
Regular Expression tables are less efficient than hash tables, but they
remove the additional dependency of having postmap command available
to Mailman. If you want to use regexp or Regular Expression tables,
then add the following to Postfix's main.cf file
My thought is adding the section header makes it more clear that
everything down to the Postfix + Dovecot section is for Regular
Expression Tables and adding the less efficient phrasing notes the
down side.
What do you think?

That is now quite clear, but I still have one question and this is cosmetic (because Postfix isn't my MTA of choice. You can ignore it if it feels like spoon-feeding a Postfix admin.
In the section:
https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.html#postfix-dovecot
.. the Postfix admin had to figure out whether they are using hash or regex tables and modify accordingly, right?
