Sentora Support Forums

Forgive me a new comer for Sentora/ZPanel. I am setting up the sentora and get some difficulties in sending email through Thunderbird:

1. I ran the install script to install sentora, didn't change anything, it works fine;
2. Use my DNS registrar to point my mail.domainxxx.com to the host ip, also associated A records are in place;
3. Target domain (domainxxx.com) is added in Sentora (but I think the mail server will be routed by my DNS registrar not from Sentora)
4. Run the build in Roundcube email client, can receive and send email without any problem
5. setup Thunderbird to use SMTP to send out and using the full email address as username in authentication without TLS/SSL, no luck can't not send out. Same thing when I tried through my iphone.

How could I fix this? Thanks!

can't access the "official docs at http://docs.sentora.io". enclosed the master.cf:

Sentora installer is still in beta so there would be some bugs.

You might try add
to your postfix/master.cf file and of course open port 587 (if needed). After that restart postfix service

In main.cf set mynetworks and mydestination to (it's mainly mydestination error):
or

and restart postfix, it's work for me.
