I am new to 3CX server. I have setup my smtp server and tested it with success.
But when I go to extension to send a welcome email I never get those emails.
Yes I am able to get the test email nothing in spam and I have added the email every place it says email. Not sure if it matters but I have a red dot next to the extension but i figured that is because the extension was not registered yet
What version and service pack are you on? Please use the gmail smtp server, you can find more details at this link https://www.3cx.com/blog/docs/gmail-mail-server/. Please let us know if the problem persists with gmail server or not.
