[ http://jira.qos.ch/browse/LBCORE-225?page=com.atlassian.jira.plugin.system.i... ] Ceki Gulcu commented on LBCORE-225: ----------------------------------- For future reference, the relevant patch can be found at [1]. It consists of removing the line which set the property "mail.smtp.auth" to true within the if(isisSTARTTLS()) branch in SMTpAppednerBase class. if (isSTARTTLS()) { - props.setProperty("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); } Tests on pixie (postfix) show that for authentication disabled server, setting the aforementioned property results in |-ERROR in ch.qos.logback.classic.net.SMTPAppender[EMAIL] - Error occurred while sending e-mail notification. javax.mail.AuthenticationFailedException at javax.mail.AuthenticationFailedException at at javax.mail.Service.connect(Service.java:306) at at javax.mail.Service.connect(Service.java:156) at at javax.mail.Service.connect(Service.java:105) at at javax.mail.Transport.send0(Transport.java:168) at at javax.mail.Transport.send(Transport.java:98) at at ch.qos.logback.core.net.SMTPAppenderBase.sendBuffer(SMTPAppenderBase.java:343) at at ch.qos.logback.core.net.SMTPAppenderBase.append(SMTPAppenderBase.java:180) This confirms the problem reported in this bug.
