An e-mail was sent from an address to another address, both on our server.
In 28 minutes on the second address were received hundreds of copies of the sent e-mail. The person who sent the e-mail said she saw the message staying in the Outbox folder from Microsoft Outlook 2003. Then she deleted the message and the flooding stopped. She recalls having the same problem once half a year ago. She has Windows XP Home with SP2 and Zimbra Outlook Connector 4.5.10. The version of Zimbra is 4.5.10.
Can you help me solve the issue?
