Hi,
I have Fedora Core 2, and it prviously has worked for sending and receiving Email, but now, after I changed the server dns information and other details, it does not want ot co-operate.
I am using WinXP with Outlook to Send/Receive Email without any success.
My mail log shows this:
[62.56.160.254] did not issue MAIL/EXPN/VRFY/ETRN during connection to
MTA
Which I gather means that the connection is lost after being started. I also can TELNET into sendmail, and do the EHLO and get the right response.
Thank you in advance.
TCPDUMP shows below: It looks like the port number is being changed by sendmail, with out WinXP doing the same.
