Topic: Global Relay Host instructions

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 0.9.8
- Linux/BSD distribution name and version: Ubantu 18.04 LTS
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx):
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

I am not very familiar with Linux as migrated from MacOS Server which is a GUI interface but would appreciate help with the Global relay host instructions from docs.iredmail.org

After following the instructions, when sending emails I get a bounce with 5.5.1 that the service requires authentication which it does, but I thought the instructions provided for authentication.

I am editing /etc/postfix/main.cf and the instructions refer to smtp_sasl instructions - everything else in main.cf has smtpd_sasl so which should it be smtp_sasl or smtpd_sasl? with the 'd'?

Where it says to write a file /etc/postfix/sasl_password with contents relay.server user:password I replaced relay server with smtp.example.com (used actual server name) and user:password with the username being my own login username myname@example.com and then the password after the colon - is that correct?

Any help gratefully received.

Thanks,
Stephen

Could you please show us the full + original error in /var/log/maillog on server?

Re: Global Relay Host instructions

Yes, I followed the tutorial at docs.iredmail.org/relayhost.html but not sure whether I should be using smtp or smtpd in those commands. (smtp_sasl_password_maps = hash:/etc/postfix/sasl_password) it would seem it should be smtpd_sasl etc as all the other lines in the main.cf are using smtpd_sasl

Here is the log from maillog:

Just copy the settings in our tutorial, and make sure you have correct smtp username and password.
