Can't telnet port 25 exchange internally
Posted on 2009-04-02
i'm having a strange problem we have a sbs 2003 r2 server. Which since yesterday can't send e-mail but can not receive e-mail. First I tried to telnet externally which didn't really respond i only get a blank prompt and not usually mail service tekst.
Also I can't ping internally from a computer. But then i thought what if I do it on the server 127.0.0.1 at port 25 but also no response.
Then i thought it was the virus / spam filter. Deleted those ones. But still no telnet connection. Now I'm beginning to get out of options.
