What exactly does the Postfix log (maillog) say about the delivery to
one of these addresses?

This normally only affects delivery TO a list in a virtual domain. If
done properly, it should not affect delivery to any non-list address
in the virtual domains.

This is almost certainly a Postfix issue rather than a Mailman issue.
If there is nothing in Mailman's smtp-failure log, Mailman has
delivered the message whith the local virtual recipients included to
Postfix and Postfix has accepted it.

See additional comments inline below.

Full output from "postconf -n" might help.

The above is backwards. It should be

add_virtualhost('DEFAULT_URL_HOST', 'DEFAULT_EMAIL_HOST')


>add_virtualhost('domain2.tld', 'domain2.tld')
>add_virtualhost('domain3.tld', 'domain3.tld')


However, nothing here affects delivery of mail FROM mailman.

Likewise, the aliases above only affect delivery TO the mailman and s
lists.

This file and its reference in virtual_alias_maps is conflicting as
this says domain1.tld is a virtual alias domain and its presence in
mydestination says it's not. Also, this is obsolete in Postfix. The
current method of specifying to postfix that a domain is a virtual
alias domain is to list it in virtual_alias_domains in main.cf.

And this virtual mapping only affects delivery to the s at domain1.tld 
list and it's associated admin addresses, but since domain1.tld is not
in POSTFIX_STYLE_VIRTUAL_DOMAINS (which is correct because it is in
main.cf mydestination which makes it a postfix local domain), why is
this list in virtual-mailman at all.
