this is the setup:
1 mailbox enabled distribution group with "send as ..." permissions for its members. One of these members sends a mail (as the distribution group) to another (internal) mailbox that also has an auto reply (NOT an out of the office, but an auto reply to every received mail). This auto reply is received by every member of the distribution group where the mail originated from. One of those members also has an auto reply active on his/her mailbox. Will this set up create a infinite mail loop or can Exchange 2003 detect this sort of thing? Is there a difference if the mailboxes are on different mail servers or on the same mail server?
