IMAP server error message - Alfresco Content Services - 23.4 - 23.4 - Ready - Alfresco - external

Exception in thread "Thread-53" java.lang.RuntimeException:
java.net.BindException: Cannot assign requested address:
JVM_Bind at com.icegreen.greenmail.imap.ImapServer.run(ImapServer.java:53)
Caused by: java.net.BindException:
Cannot assign requested address: JVM_Bind

This error message is related to the IP address or hostname that has been provided for binding. To resolve this issue:

• Check that the IP address or hostname you provided is correct for your imap.server.host setting.
• Check that the port you’re using is not blocked. The default port to use is 143.
• Check that firewalls are not blocking this IP address or hostname.

• Use the command line tool Netstat to check your network connections.

  Note: You should not use localhost as the imap.server.host - update this value with the IP address (or corresponding DNS address) of your external IP interface. A value of 0.0.0.0 in Unix will make it listen on the specified port on all IP interfaces.
