No SMTP server defined

KB Home   |   No SMTP server defined

When setting up PaperCut’s Email Notifications customers may experience an issue when using some types of Antivirus/Malware software that intercepts SMTP connections.

Error sending email: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 550 No SMTP server defined. Use real server address instead of in your account.

The above error message indicates that the Java backend of PaperCut is refusing to use as a SMTP server. This has previously been caused by the Antivirus software intercepting the SMTP connection and redirecting it locally rather than to the customers specified SMTP server.
