Hi,

My company is having a strange issue with sending email to a particular person. Comes back with this error message:-

Your message did not reach some or all of the intended recipients.

Subject: test email
Sent: 07/08/2007 16:51

The following recipient(s) could not be reached:

[email protected] on 07/08/2007 16:51

This is happening to all users trying to email this one person, even stranger is that we can email other people on the same domain and when we use something like hotmail we can email this person fine.

any ideas? Thanks
 
Are they in an exchange organisation too?

Has this person in their company set some obscure rule to not allow any emails from your company (this can be done locally as well as through EMS).
 
is your exchange server responsible for distributing all incoming emails? or do you use a third party remote server? perhaps they have to be added to that?

also is this an ongoing problem? i.e. is he a new employee and this has happened from day 1 or did it just randomly occur?
 
but could he have done it accidentally?

Unless some obscure setting for that explicit user has occurred in your EMS then I can only assume the receiving user has generated some setting unknowingly.

Can you create a POP3 email account with your Domain ISP and send to him that way?
 
Hi

check your Exchange SMTP logs and also speak with the Exchange Admin at the other end to check theirs - could be this user has black listed you for some reason.

If everyone in your company cannot email this domain - I would first check it out with their Exchange Admin to make sure the MX records are ok their end and that their not having any mail flow problems.

I take it your rDNS is ok too? Some mail servers will drop mail if the rDNS is not correct
