Fix Hestia Email Issue
Budget: $30 – $250 USD
I can only receive emails but not send any. Hestia was installed on Ubuntu 20.04. See error:
Remote-MTA: dns; gmail-smtp-in.l.google.com
Diagnostic-Code: smtp; 550-5.7.1 [xx.xxx.xx.xxx] The IP you're using to send mail is not authorized to
550-5.7.1 send email directly to our servers. Please use the SMTP relay at your
550-5.7.1 service provider instead. Learn more at
