    <p>I used to run a server app that sends an e-mails each 2 hours, but sometimes i get the error below:</p> <pre><code>Não foi possível enviar a mensagem. Mensagem: com.sun.mail.smtp.SMTPSendFailedException: 550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1) Jan 07, 2013 1:00:32 PM job_hidrojato.comunicacao.email.Email run SEVERE: null com.sun.mail.smtp.SMTPSendFailedException: 550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1) at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388) at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959) at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583) at javax.mail.Transport.send0(Transport.java:169) at javax.mail.Transport.send(Transport.java:98) at job_hidrojato.comunicacao.email.Email.run(Email.java:186) at java.lang.Thread.run(Thread.java:722) </code></pre> <p>I've already tried to explicitly define the mail.smtp.localhost using the code below, where "HADES" is the hostname of my server, but it didn't work.</p> <pre><code>props.put("mail.smtp.localhost", "HADES"); </code></pre> <p>The error log gerenated after this change is the same, so I think that the problem isn't the hostname parameter. I already read the links below but again, didn't work, so I'm running out of alternatives to solve this problem, and any help would be appreciated :)</p> <p><a href="https://stackoverflow.com/questions/4934373/invalid-helo-name-in-javamail">Invalid HELO name in JavaMail</a></p> <p><a href="https://stackoverflow.com/questions/8542616/550-access-denied-invalid-helo-name">550 Access denied - Invalid HELO name</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
