If I retry the mail, it does nothing.  I have telneted successfully to the
box and have sent several messages with no issues.
 
Good ideas though...
 
I have even gone as far as rebuilding the IMC on the server.

Instead of deleting the message, retry the delivery.  Your relay server may
have reached its max number of connections or is too busy.  

 

 

Also try telnet'ing to that box (port 25) and test sending a message...
This might give you a better clue as to what is causing the connector to not
reach that server in a timely fashion.

Hello all,

 

Basic Setup info (for outgoing mail)

    running Exchange 5.5 on Win2K.

    I have an internal Bridgehead server that is setup to forward all mail
to a GFI MailEssentials\Security Gateway(via IP) box for SPAM\Virus
scanning.  

    The GFI software then sends the mail using SMTP in IIS

 

Issue:

   Our systems send on average 40,000 e-mails per day.  Every day, at
various times, I will look at my Performance Monitors for the queued
outbound messages on the internal Exchange 5.5 bridgehead server.  About
twice a day, I will notice that the queue will show one message stuck in
queue.  If I let it sit there for about an hour, about 10 to 15 e-mails will
queue up behind the other mail.  Keep in mind, that our organization is
still able to send and receive mail through this very same server(except for
these random few messages that are queueing).

 

   When I look in the outbound queue in the Exchange Administrator then
click on the message itself, the details screen appears.  In the Recipients
field it lists the destination address followed by [Host Unreachable].

 

   If I delete the first message (by time submitted) the remaining queued
messages are sent.

 

My questions are:

1.  what could be making mails queue up in the Exchange IMC if it is
configured to send all e-mails to the GFI gateway server for delivery?

2.  what would cause the random few messages to queue up behind this message
even though 99% of e-mails are flowing as they are supposed to?

3.  why would the Exchange IMC find the Host Unreachable since it is not
setup to send mail other than directly to the GFI gateway IP Address?

 

Weird issue...

 

Thanks for any ideas.


Chris
