    Hi,

    Our users have reported problems with sending e-mail messages to any address at HotMail.com. Apparently, it does happen on several cPanel/Exim servers. The logs are reporting:

    2006-07-18 10:36:36 1G2qgb-0008QM-SE ** hotmailuser@hotmail.com R=lookuphost T=remote_smtp: SMTP error from remote mail server after RCPT TO:<hotmailuser@hotmail.com>: host hotmail.com [69.93.140.34]: 550 unknown user

    Now, when sending a test message FROM HotMail account:

    2006-07-18 10:41:17 H=(bay0-omc2-s38.bay0.hotmail.com) [65.54.246.174] sender verify fail for <hotmailuser@hotmail.com>: response to "RCPT TO:<hotmailuser@hotmail.com>" from hotmail.com [69.93.140.34] was: 550 unknown user
    2006-07-18 10:41:17 H=(bay0-omc2-s38.bay0.hotmail.com) [65.54.246.174] F=<hotmailuser@hotmail.com> rejected RCPT <ourlocaluser@ourlocaldomain.com>: Sender verify failed

    It does not matter to which HotMail user the e-mail is sent - the error still is the same.

    Does anyone experience the same situation?

    Looks like there is an account setup with a domain name hotmail.com on the 69.93.140.34 server. You may want to investigate this.

    Sparek-3,

    That was it - the "hotmail.com" was setup locally - strange since we have tweak "Prevent users from parking/adding on common internet domains. (ie hotmail.com, aol.com)" enabled.

    Sending TO "hotmail" account now works but FROM still returns error:

    2006-07-18 11:41:14 H=bay0-omc1-s34.bay0.hotmail.com [65.54.246.106] F=<hotmailuser@hotmail.com> rejected RCPT <localuser@localdoimains.com>: Sender verify failed

    I have noticed that e-mail will go through only when disabling Exim option "Verify the existance of email senders". But, is it is safe to have it disabled?

    Thank you.

    in exim.conf, add the instruction "interface"

    remote_smtp:
    driver = smtp
    interface = IP-SERVER

    restart exim

    Works 100%

    becareful if you modify manually exim.conf, you will loose the modification in the next cpanel upgrade
