Address Management Tips

Successfully maintaining an error-free e-mail list requires an effort consisting of one part detective work, one part communication skills and three parts persistence.

Invalid Addresses:

Different e-mail servers respond to invalid addresses using different messages.

Bad address indicators include but are not limited to:

• User unknown
• 550 MAILBOX NOT FOUND
• The recipient name is not recognized
• The following addresses had permanent fatal errors
• reason: 550 Address not known at this site.

Response is the same for all of these examples: Identify a valid address and correct the current entry. If a valid address cannot be determined, remove the address from the list and re-add the individual when the problem has been resolved.

Other situations:

Host unknown (Name server: inbound.chickmail.com.criticalpath.net.: host not found)

The Host Unknown error refers to the second half of an e-mail address. In this instance, because the message was sent to a GatorLink address, the problem is associated with the target of a forwarding setting.
 
Forwarding may also be involved whenever a particular address is reported as an error but the bad address isn't found to be a member of the list. The unit's phonebook coordinator may be able to associate the bad forwarding address with an individual faculty or staff member by manually reviewing everyone's settings but will not have access to.

 

Host unknown (Name server: ufl.ed: host not found)

A misspelling is one of the simplest errors to correct. Edit the individual's address in the list by adding the missing "u" as in: "ufl.edu"

UserID: Over quota

(UserID@ufl.edu)... Deferred: cyrus mailer (/usr/opt/cyrus/bin/deliver) exited with EX_TEMPFAIL

Message could not be delivered for 5 days

Message will be deleted from queue

Regardless of the host e-mail system being used, some people use up their allotted space. When this happens, the preceeding error message indicates their mail box is full. No new messages will be accepted as long as the mail box remains full. The only possible response is to contact the individual (i.e., UserID) who must delete messages to make more space available. In some cases, the person may have to contact their e-mail provider for additional assistance.
