Please send me in private e-mail an example of the exact error message that you are getting from emails being rejected.
I am part of the Santa Clara County team maintaining the JNOS BBS systems here, and this aspect has been running mostly unchanged for several years now. We are publishing SPF and DKIM records for our ampr.org and "native" hostnames in DNS. I am not aware of any new or recent failure modes.

This may be beyond the scope of some since I mentioned JNOS, but the basics should be the same. I have been running the n2nov.ampr.org JNOS system since the late 90s, but recently any emails that I send to GMAIL and some other services are being rejected. The same happens when any email is sent to me from those same commercial SMTP services. This is all boiling down to the modern SMTP security functions are not part of JNOS. It has been mentioned that I should use the Postfix on the CentOS server that it sits on as it is already servicing various accounts that I maintain for clients and amateur radio groups. If someone else is using this arrangement already, I would like to see how you are doing it and what the limitations are. I believe the Santa Clara group was going to implement something like this a few years ago. Thanks in advance.
