While you're waiting for a real TCP-knowledgeable person, have you tried using _INetSMTPMail to send an email through the server? You can look it up in the User-Defined Functions section under INet. Knowing whether this does or doesn't work might provide a clue.

Also, which error code are you getting back from TCPConnect?

That's weird. If TELNET fails on port 25, blat shouldn't be working.

Are you sure you are using port 25 on TELNET?

telnet servername 25 to connect.

hi guys

i've a problem with smtpmail yes, but the error comes down with tcpconnect

the error returnent with the tcpconnect function is 10053 :

Question/Problem: WSAECONNABORTED (10053) Software caused connection abort.

Answer/Solution: A connection abort was caused internal to your host machine. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections.

WinSock description: The error can occur when the local network system aborts a connection. This would occur if WinSock aborts an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket).

TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK)nowledgement for data sent. It would also timeout if a (FIN)ish TCP packet is not ACK'd (and even if the FIN is ACK'd, it will eventually timeout if a FIN is not returned).

i've tried with ethereal, but i did not try to follow tcpstream, because it appears just two lines of ARP packets, between me and the server. no the server isn't using tls or ssl, because blat doesn't need it

here is the capture with blat :
