My exchange 2003 environment forwards the e-mail to a Smart Host running
IIS 6.0 SMTP services with GFI.
When the users with the apostrophe in the e-mail address sends the
message, I can see in my SMTP logs (on the Smart Host) that the e-mail
attempts to deliver and the session just quits unexpectedly.
GFI is not stopping the mail delivery, but the SMTP session never
completes and the e-mail appears to simply 'disappear' with no bounce
back or error.
When I change the Primary SMTP address to NOT contain the apostrophe,
all works well.
Any ideas?
Thanks,
Chris

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
