Ottawa Canada Dear David and list: You receive out of office replies when you post a message to a list such as this one because of Brain dead vacation programs! This is the name of the program that responds to incoming e-mail with a message that the recipient is away from the office for a while and urgent matters should be directed to so and so in their absence. This program is not supposed to respond to e-mail received from a list such as a Freelists or Listserv managed list. However over the years various programmers have forgotten this little point and written versions of the program that happily respond to each message they receive while the person is flagged as being away. There used to be an option in this program to limit its auto-responses to say once per day to a given correspondent, once a week or even once a month. However it seems many implementations of it now happily auto-respond to each and every message they receive, even if from the same sender 15 seconds apart! Some interesting infinite loops can be created if you send an e-mail to someone on vacation say just after you set your computer to say you too are on vacation! Originally mail from mailing lists had a keyword inserted into its subject field that was a tip to the vacation program to NOT auto-respond to it. The word was [bulk] but it seems the people who write list management programs and auto-response programs have forgotten this gentlemen's agreement years ago. Oh and one little thing some mail systems don't do right is to send trouble reports regarding the delivery status of a message, such as a delay or inability to deliver it to the SENDER of a message, not to the person it is FROM: I'll explain this: The message is from its author but may be sent on their behalf by someone else. Normally the from and sender are one and the same, but mail from a list is sent out over the list by the list management program although it is from its author. So if a mail system cannot deliver the message or will have a delay in doing so, it should advise the SENDER of this as the author may be a good rocket scientist or M. D., but not know much about computers and e-mail problems. This spec is enshrined in an actual RFC, the 822 spec which deals with the addressing and handling of e-mail. I've seen various e-mail programs that don't implement it correctly and when I advise the site's Postmaster, of the spec and particular item in it, they generally tell me they will take up the matter with their software vendor or publisher. If everything on the Internet worked the way its creators intended, you wouldn't receive out of office auto-responses to messages sent out over a list. Sorry for the long winded explanation, but some things require a thorough explanation. Brian Brian K.
