Sent from email address is using random address names

[Randy Clark]

We are having issues with the "sent from" email address on emails from Jira. It is showing random email names. This started occurring around April 11th-15th but only on a few emails. But it has occurred more frequently since that time to almost 100% of the time now. Any reasoning why this is occurring?
