I have CentOS 7.3.1611 installed and there I have Icewarp mail-server installed.



When the firewall is stopped, I can connect in my web browser to the admin console, but if it is started then I can't connect to this web console. I probably have to add a rule for this address: http://random.random.net (or https). Maybe is just needed enable ports 80 and 443 which are for http/s?



Can you please help me to solve this issue or state how add this firewall rule?




centos firewall

    what are you connecting to on which protocol on which port ? what is your current firewall ? what is its current configuration, it's impossible to help without a bit of background here.

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
