Hi Jeremy.
Removing localhost from mynetworks means that if any local process sent
emails through this MTA using SMTP to 127.x.x.x,
Took out localhost references from mynetworks on the ciphermail host and now
it’s doing what I think I originally expected:
May 21 22:38:17 cmx01.la1.blah.com postfix/smtpd[322660]: NOQUEUE: reject: RCPT
from localhost[127.0.0.1]: 554 5.7.1

Yes, you ave a mailer loop.
mx1 Receive 7B34152BBDB (2326 bytes) from macbook
mx1 Deliver 7B34152BBDB to content filter, receive as B8C5452BBDF (4004 bytes).
mx1 Deliver B8C5452BBDF to cmx01 as 4L4tdt0Fk8z2SSLv
cmx01 Receive 4L4tdt0Fk8z2SSLv (4998 bytes) from localhost which was sent to

Don't forward mail that for which the input MTA is expected to be the

Maybe I'm misunderstanding, but my interpretation is that the question is
"why are you accepting that mail?" and saying

I’m seeing an interesting problem due to the fact that aws ip’s are so heavily
