      Had no problems with ppp. Ran and update and it stopped working.

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
