Topic: Not sending mail from local network

[del_piero]

Hi all.
It´s my first post here, however i´m always here looking from sugestions from you guys.

My problem is this:

I have a sme box with release 6.0.1-01 that´s have been working for the last 6 months without any problems, until the hdd fried up... Now i´ve put another hdd and with the same release the mail´s from local pc´s are not going out. My isp has not block traffic on port 25, that´s for sure!!! I send the mail from outlook 2003 and instantly i receive a message telling me this "553 Sorry, that domain isn't in my list of allowed rcpthosts" . But if i send the same mail for the same e-mail address frow webmail, then it goes out!!!! I can´t understand what is wrong!!! From webmail works, from local pc´s (outlook 2003) don´t work!!! Why??? Can you help me??? I think that the sme box doesn´t recognize the local network!!!! Thanks in advance....Btw, the server is working in server only mode.
