Hello, I'm trying to set up SMTP feature... I open sysconfig->Framework->Core::Sendmail And I set: SendmailModule: SMTP (because I've an external smtp server) sendmailModule::CMD: /usr/sbin/sendmail -i -f (but I think it's not necessary right?) SendmailModule::Host mail.netsons.com Port: 25 AuthUser: support-system+netsons.com (it's an erro +netsons.com?) Password: mypassword others fields are blank (I don't write) When I try to send an email : Can't send to: ethernaly@email.it! Enable debug for more info! If I use in AuthUser: system-support (without + or @ netsons.com) this is the error: Errore: SMTP authentication failed! Enable debug for more info! So I think + netsons.com is necessary, but where is my error? Sorry for my english I hope in your help
