Question: Are there specific setting for using the Email Import in a multiserver environment.
Answer: While the optimal configuration would be to only have email import configured to run on one server in a multiserver environment, if you do choose to have the email import running on multiple servers, we recommend that you stagger them by at least 5 minutes. It’s best to have them check every 10 minutes and have them stagger at 5 minutes from one server to the other.
Multiserver:
dcma.importMail.cronExpression=0 0/10 * ? * *
dcma.importMail.mailProcessCronExpression=* 0/10 * ? * *
