Hi, I'm setting up OTRS with a system email account that is a lotus account. I'm quite sure I have the right settings in place in the sendmail module, but when I try to send a mail using the admin notification tool, I keep on getting this error. Does anyone have any suggestions on what I should do? Thanks Emily Error: SMTP authentication failed: 500Command unknown: 'AUTH'!
