phpBB and SMTP

I need help setting up SMTP on phpBB (which I installed through cPanel) so I, as webmaster, and the registered users, can get email notifications.

 

For phpBB's email options, I've set the SMTP server to localhost and the port to 25 as specified in this message. However, my emails aren't being sent, and when I view the error log, I see this:

Backtrace
Connecting to localhost:25
LINE: 1205 <- 220-a2plcpnl0376.prod.iad2.secureserver.net ESMTP Exim 4.92 #2 Sun, 14 Jul 2019 23:22:30 -0700 
LINE: 1205 <- 220-We do not authorize the use of this system to transport unsolicited, 
LINE: 1205 <- 220 and/or bulk e-mail. 

Is there a way to get SMTP to work?

Don't rely on SMTP unless you own the SMTP server with a dedicated "safe" IP...

 

Otherwise, it may just get blocked or marked as a spam.

Re: phpBB and SMTP

I'm curious then, what is the alternative solution that is available? Thanks. I'm running into the same errors causing users of my discussion board to miss important notifications. 

 

EDIT: Actually I'm receiving a different error. Apologies. Perhaps the solutions would be similar. Thanks for your advice. I'm running phpBB using "localhost."

Use services like SendMail, MailChimp, SendGrid etc... They have free tier that are in the thousands.
