Outgoing mail does not work in JIRA. Error messages like the following appear in the logs:

com.atlassian.mail.MailException: com.sun.mail.smtp.SMTPSendFailedException: 452 4.3.1 Out of memory


The outgoing mail server (not JIRA) is running out of memory.


The problem must be resolved by administrators of the outgoing mail server. Please refer to Microsoft's document for more information.
