Mail Server Failed

Hello All,

Recently, I tried my hand at installing Lucee on a Windows server. I’m trying to set up the mail server in Lucee (version but I keep running into this message.
Verification of mail server [ ] failed:
can’t connect to mail server

I don’t have direct access to the mail server but I did get the information IT.

I only was given the SMTP and port there is no username.

Thank you for any assistance.

Don’t forget to tell us about your stack!

OS: ???
Java Version: ???
Tomcat Version: ???
Lucee Version: ???

Maybe a blocking firewall? Are you able to connect to the server with command line with telnet SERVERNAME 25 ?

What version of Lucee are you running? There seems to be an issue with newer versions where it cannot connect. Downgrading to 5.3.5 (i think) works


I’m using version


I have not tried connecting to the server with command line talent… I’m not sure I know how to do so.

I’ve found a link with a good step by step instruction for you.

Check also the complete stack trace (error) because it might also be some handshake TLS/SSL problem.
