(n)upas/ml quirks

The presence of a host!user formatted address in a mailing list's address-list file seems to prevent an incoming message from being delivered to the list.

I have not had a chance to investigate this further. The empirical test was to remove the host!user address from the 9front mailing list's address-list file, at which time messages stopped being dropped silently and resumed being delivered to list members.

any messages in /sys/log/mail about this address?

i looked into mail/ml and all it does is to call upas/send with
the list of addresses as arguments and the mail to be send is
read from standard input. upas/send resolves each destination
individually... not clear why this would break all the destinations.

shouldn't all the outgoing mails be queued anyway? and processed
asynchronously? can you try and run upas/send with the bogus
destination in question and see what happens?

I'll try all these suggestions. I ran out of time yesterday.

One note:

The offending address was actually an *unsubscribe*:

        !host!username

The original subscribe appeared in this format:

        user@host

I was monitoring logs while sending test messages and it appeared‎
that the message was accepted into the system but was never
sent out to address-list.

It also appeared that the list's pipeto was not fully processed; ‎some
of the intermediate files created by the list's pipeto script never got
created (until I removed the !host!user line from address-list). This
makes me wonder if the failure occurred before sending was even
attempted.

As I say, I ran out of time, but the seeming failure to handle the
address-list seemed like a clue. I think I recall previous observations
of a similar failure: a mismatch between subscribes and unsunscribes
results in failure, generally.

I'll have more medium- to low-quality observations to report tonight.

lines starting with ! are removed entries... the address
list is just a log of added and removed email addresses...

i dont see why using host!user syntax would not work... rewrite
should handle this and convert it back to user@host.

do you mean like if theres a unsubscribe but no matching subscribe it
results in the mailinglist being broken?

or you mean that when the strings do not match the sender is not removed
from the mailinglist?
