    Im not sure where to post this question;

    I have a webhosting customer, this customers has multiple email addresses i.e. him@hiscompany.com, hisbrother@hiscompany.com, etc. this is a new account and since switching to our hosting service he that says that he can send and receive email to and from outside of his office but if he sends a message to anyone in his office with the same domain name it does not get sent or received,
    Also there is no error message of any kind?

    Thanking you in advance.

    Charlie

    Outlook settings?

    Where would we begin to look, and what are we looking for?

    As you told that you are able to use your email account outside the office. So, I think you have not configured email settings properly. Are you getting any error?

    There are no errors at all it just acts the same way it acts when sending a message to someone outside?

    1. Are the authoritative nameservers listed in his domain's WHOIS information the proper nameservers? They should be yours.

    2. Is his domain(s) in your /etc/localdomains file? They should be
    3. Is his domain(s) in your /etc/remotedomains file? They should _not_ be

    4. How are his email client settings configured?
    - typically it would be mail.domain.ext for the SMTP/POP3

    5. Have him open a DOS prompt and then do:

    nslookup mail.hisdomain.com
    ping mail.hisdomain.com

    An nslookup of mail.hisdomain.com (from HIS computer in his office) should return the IP address of his mail server that is on YOUR machine. If ' nslookup mail.hisdomain.com' (from HIS computer) does not return an IP address on YOUR server, then one or more of the following is true:

    a. his ISP is caching old DNS information
    b. he has a local dns server / router doing dhcp and dns that is storing cached DNS information
    c. he has hardcoded mail.hisdomain.com to an IP address on his local machine

    Have the customer (a) shut down all machines in his office, (b) reboot his router/IAD, (c) turn his machines back on, and then (d) try to send/receive mail.

    I am _guessing_ that invalid DNS information (related to mail.hisdomain(s).com ) is being cached on his computer, his router/local dns server, or his ISPs nameservers. He can send to others, but when he attempts to send to somebody in his domain, it connects to his old account somewhere else maybe?

    Charlie,

    There must have been some result.

    When they did "nslookup mail.theirdomain.com" from a computer that they were sending mail from, did the IP address that was returned match the IP address of your server?

    It really sounds as though they are connecting to a server somewhere else (perhaps the server that used to house their account). I don't believe they are connecting to _your server.

    I'd be glad to dialog more, and in fact even try to assist - I don't know how trustworthy you deam other people as far as access to your server. if you want my help/diagnosis, just PM me. I'd need to have access to your server, or at the very least I'd need to be able to see the logs that are generated on your srever from SMTP/POP3 transactions.

    I'm not totally convinced they are hitting your server. But if they are, I am quite sure I can figure out what the problem is.

    Mike
