[Dnsmasq-discuss] strange list server bounces

[starlight at binnacle.cx]

Hello,

A problem of some sort exists with the list
server configuration.  All messages submitted
from here bounce when relayed by a mature
'sendmail' configuration.  Only way to submit
messages is manually using 'nc' directly to
one of the MX servers.  Bounce message example
follows.
