The tech support person I spoke to today tried setting
MaxRecipientsPerMessage in the /etc/mail/sendmail.cf file to 20 as in below:
# maximum number of recipients per SMTP envelope
O MaxRecipientsPerMessage=20
But that didn't seem to help. Thanks for your suggestion about
bulk_mailer and TLB. It would probably take some trial and error since
the tech support fellow indicated that the anti-spam measures (e.g.,.
how many recipients are in fact allowed per message) are kept secret
from him and other tech support people.
Ultimately, he was able to provide a solution that, for now at least,
successfully routes our messages around their relay that had been
blocking list mail, so for now I guess I'm okay. Thanks again for your
suggestion, Dan, which may come in handy later on.
