Hello,

 

Was anything changed 5 days ago?  Exchange itself, domain controllers or
global catalog servers or a firewall change?  Did this change affect sending
to all external recipients of specific ones?

I would be interested in seeing the bounce.

 

RFC-2822 says that character is OK. That doesn't mean all mail systems along
a path would.

Hello all,

 

   Running Exchange 2003 Pre SP1...

   

   I have several users that have (for years) had an apostrophe in their
primary SMTP address, and they have had no problems. An Example would be
Chris.D'Wall@xxxxxxxxxxxxxxxxxxxx  Notice the ' in the example.

 

   All of a sudden, 5 days ago, all users with apostrophes in their SMTP
address have been unable to send external or receive external e-mails.  To
fix the issue I have had to set their primary SMTP address to not include the
Apostrophe.  Using the example above, the new primary would be
Chris.DWall@xxxxxxxxxxxxxxxxxxxx  

 

   This would allow mail to flow from and to the users.

 

    Now the weird part - if I leave the Chris.D'Wall@xxxxxxxxxxxxxxxxxxx
address as an alias - external senders can now deliver mail to either
address. 

 

Any ideas on this one?

 

Thanks

Chris
