My users are getting the following message being bounced back to them quite often (I edited out identifiable information and used <> to insert descriptions) - MailEnable: Message delivery has been delayed. Message is waiting at <server_name> for delivery to <recipient's_domain_name>. Reason: Mail Server for <recipient's_domain_name> could not be contacted at this time. MailEnable will keep trying to deliver this message and will notify you of any progress. My question is, can this be stopped or delayed longer than 30 seconds after the message is sent? It seems to be creating a lot of excess mail. Could this be a configuration problem?
