Issue Error 454

dyrer

Basic Pleskian
Hello
I have Plesk Onyx with Centos 7

I need you help, appreciate
 
Do you mean sending email through the webmail like Roundcube? Or how it can be reproduced?
 
I use cloudflare for DNS I dont know if this creates the error
I have modified just now and i wait if works
This command didnt help :( neither
 
Hi dyrer,

pls. provide your current log - file ( "/var/log/mail.log" / "/var/log/maillog" ) - entries and the correponding configuration files ( main.cf + master.cf from "/etc/postfix" ), if you experience further issues/errors/problems, after following the suggestions from the already provided forum - link. People willing to help you should have something to investigate based on facts and describing the issues/errors/problems might not be sufficient "to guess" your root cause. ;)
 
Through outlook using mail.domain.tld
In Outlook, many people don't check the "Outgoing mail server requires authentication" checkbox, because it is not obviously displayed in the assistant dialogue. As in the default setting, Outlook does not authenticate at the SMTP server, relay access will be denied. Simply checking the box will probably solve the problem.
