the user has a group of people that she is sending to and about i would say 100 people and a majority of them go through and some do not bouncing back and saying user cannot send to this recipient.  she is sending the mass email out to multiple people on multiple external domains. i.e. comcast,juno,etc.

thanks

ok i went to a tool on the internet to see if our server or our recipients were on any blacklist and they are not.  so i am going to try and check the ip's that the messages are being sent to to see if i can find anything else out.

any suggestions????

Without the exact text of the error messages the sender receives, diagnosis is quite difficult.

the internal domain is .local and the external is .org.  dns is configured to use forwarders to our isp who hosts our dns

The reason for your messages being bounced is quite clear - it is exactly what the error message says. Your server is telling the world its name is something.local, which is not valid on the internet. As a common antispam technique is to check if the sending server is valid, you fail on those tests.

You need to get your server setup correctly before you get blacklisted.

ok.  this scares me.  on everyone else.  when they send out an email.  i do not or they do not get this error.  does this mean there is something wrong with the account??  what about changing the smtp banner to advertise the server??

You don't have to rebuild the server.
The way the server is announced just has to be changed. Fairly standard change that has to be made.
It has nothing to do with the account, and I am surprised that you haven't seen the message before because it is a standard test. You obviously do not send to AOL.com accounts or any of the other major email providers as that would cause those messages to be dropped.

oh thank god i do not have to rebuild.  ok so i have to change how the server is advertised.  so the way i know how to do it is to change the metabase.xml file, using the code 36907, save the file and restart smtp service.  do you know a easier way of doing this???

amoosAuthor Commented:
by changing the smtp banner or the way it is advertised to the outside will that effect anything on the internal domain side since our interanl domain is .local and external is .org??

in the metabase.xml file that i can edit there are two entries, 1)36935 that has the .local address 2) i will add above that the 36907 entry for the servername.mydomain.org.  do i need to leave the .local in there or delete it??

SembeeCommented:
Why are you looking at the metabase?
If you read the article I linked to above I have identified where you change the entry in ESM.
