One of my machines is seeing the following from Courier (0.45.4):
220 hermes.affidian.com ESMTP helo bucky.affidian.com 250 hermes.affidian.com Ok. mail from:<[EMAIL PROTECTED]> 517-Domain does not exist: bucky.affidian.com. 517 Invalid domain, see <URL:ftp://ftp.isi.edu/in-notes/rfc1035.txt>
Hermes is in my DMZ, Bucky is in my private network. Hermes doesn't know anything about Bucky (i.e. Bucky is not in in the DNS view that Hermes uses.) Other machines in my private network (same subnet) that _are_ resolvable by Hermes do not show this behavior.
Per my reading of INSTALLATION, I added ".affidian.com" to esmtpacceptmailfor and reran makesmtpaccess. After bouncing Courier, I'm still experiencing the same behavior.
I don't want to eliminate the "bucky.affidian.com" ([EMAIL PROTECTED] sent from bucky works fine) and I don't want to put all the machines that _might_ send a status message to root/me in DNS.
Any suggestions? Did I misread the docs?
esmtpacceptmailfor has nothing to do with the sender's address.
You have the BOFHCHECKDNS option enabled by default.
As such, unresolved sender addresses are rejected.
