Hello All,

I'm having difficulty with using the SMTP module to send mail from our site.

1.) Sending mail from my dev machine. The dev machine is on the same network as the email server I'm attempting to use to send email. Using this machine gives me zero problems - I can send mail flawlessly.

2.) Sending mail from our live site. The live site is hosted by a third party (domain.com). We're still trying to use our own email server that we host. And using the same settings as my dev machine, I can't get email to work at all. (I get the authentication issue). The debug information from the module gives me this line which caught my eye: SMTP -> ERROR: Password not accepted from server: 535 Error: authentication failed.

I've done a lot of reading but can't really figure out where to start. From the details I've given - and any previous experience - does this sound like an issue with our email server (or possibly firewall?) or is there an issue with our hosting account?
