This should not change anything for StrongView customers at this time.
AOL Changing Mailer Daemon Error Senders
Posted Jul 21st 2009 4:05PM by Christine Borgia
AOL is making a change which will affect the behavior of ALL bounce messages for both inbound and outbound mail.
Currently all bounce messages have the sender name of MAILER-DAEMON@aol.com.
With the changes for outbound mail, ALL bounce messages will have the sender name of MAILER-DAEMON@sender-domain. For example, an AIM account sending invalid recipients to the internet, will receive a bounce from MAILER-DAEMON@aim.com, and a switched.com member from MAILER-DAEMON@switched.com, UK member from MAILER-DAEMON@aol.co.uk.
With the changes for inbound mail, ALL bounce messages (mostly due to user-defined spam settings) will have the sender name of MAILER-DAEMON@recipient –domain. For example, a member of yahoo sending to an AIM account with a user-defined block, would receive a bounce message from MAILER-DAEMON@aim.com.
This may result in multiple bounce messages generated for a single piece of email being returned to the same sender. One bounce message is generated for each unique recipient domain.
For example, a member of yahoo sending a message with four recipients, two AIM accounts and two switched.com accounts (all with user-defined blocks), would receive ONE bounce message from MAILER-DAEMON@aim.com and ONE from MAILER-DAEMON@switched.com.
These changes will be installed into production over the next couple of weeks.
