*Topic*: caArray Usage

*Release*: Up to caArray 2.x

*Date entered*: 01/13/2010

h2. Details about the Question

The User Registration page shows the following error message at the top of the page: "Unable to send the confirmation email". The user found the following relevant error in the log file:

{code}2009-12-09 13:48:45,765 ERROR [gov.nih.nci.caarray.web.action.registration.RegistrationAction] Failed to send an email com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first. 23sm72910qyk.3{code}

h2. Answer

This problem was due to incorrect mail parameter settings. The following two parameters were incorrectly set to be:

mail.smtp.auth=Yes
mail.smtp.starttls.enable=Yes

The correct value should be "True" or "False". 

|| Parameter||  GUI Installer Text || Description|| Permissible Value ||
| mail.smtp.auth | "Mail Server Authentication" | Whether or not the mail server should be authenticated against. | "true" / "false" |
| mail.smtp.starttls.enable | "Mail Server starttls" | Whether or not the mail server should be communicated with using Transport Layer Security (TLS). | "true" / "false" |
