Hello,

I've received a question from a list subscriber about whether the unsubscribe notification that they received (below) is legitimate.  I do not believe it is, since the list in question is not configured to auto-delete subscribers.  But why would the subscriber have received this?  Can anyone shed some light on this?

Thank you,
Scott

Subject: Your removal from the XXXXXXXXX list

Sat, 11 Jun 2011 00:54:10

You  have  been automatically  removed  from  the XXXXXXXXX  list (xxxxx.)  as a  result of  repeated delivery error reports from your mail  system. This decision was based on the automatic error monitoring policy in effect for the list, and has not been reviewed  or otherwise confirmed  by a  human being. If  you receive this message, it  means that something is wrong: while  you are obviously able to receive mail, your mail  system has been regularly reporting that your account did not exist, or that you were otherwise permanently unable to receive  mail. Here is some  information which may assist  you or your local help desk in determining the cause of the problem:

- The failing address is [log in to unmask]

- The first error was reported on 2011-06-06.

- Since then, a total of 2 delivery errors have been received.

-  The   last  reported   error  was:  5.0.0   550  during   RCPT:  5.1.1
<[log in to unmask]>:  Recipient address  rejected: User  unknown in virtual alias table

PLEASE DO NOT  IGNORE THIS MESSAGE. While you can  of course re-subscribe to the list, it is important for  you to report this problem to your mail administrator so that  it can be solved. This problem  is not specific to the  XXXXXXXX list,  and also  affects your  private mail.  This means  that YOU  HAVE PROBABLY  LOST SOME  PRIVATE MAIL  AS WELL.  Anyone trying to  write to  you during  the same time  frame will  probably have received the same errors for  the same reason. The XXXXXXXXX list is but one  of the many people who  may have tried to write  to you while your mail system was malfunctioning.

DO NOT LET TECHNICAL PEOPLE CONVINCE YOU THAT THIS IS NORMAL. It is never normal for a mail system to claim  that a valid, working account does not exist, just as it would not be  normal for the post office to return some of  your mail  with  "addressee  unknown" when  the  address was  written correctly.  It is  true that  some mail  systems are  less reliable  than others, and your technical people may be doing the best they can with the tools  they have.  But, ultimately,  the level  of service  that you  are receiving is the result of a  business decision, and not something due to a universal technical limitation that  one can only accept. Reliable mail systems do exist, and  it is ultimately up to you  to decide whether this level of service is acceptable or not.
