that is not the case here. i am on a router and if i open a session in a browser there is no delay.

plus, thw wireshark trace shows that the delay is after the SMTP connection has been established, so i can hardly be a DNS problem, i think.

i just tested one other thing: the problem is the same with a different mail server. so it seems it doesn't hinge on the server.

I had similar problem. I had no DNS address and DNS alternative in XP TCP/IP of connection (Internet LAN Gate). Setting it helped.

hi,

since some time (months now, i can't remember when it started) i have a delay about 10-15 seconds long when i send mail with SMTP.  the bat log says:

03.12.2009, 18:10:51: SEND  - sending mail message(s) - 1 message(s) in queue
03.12.2009, 18:10:51: SEND  - connected to SMTP server
03.12.2009, 18:11:03: SEND  - authenticating (plain)...
03.12.2009, 18:11:03: SEND  - sending message to xxx
<03.12.2009, 18:11:04: SEND  - message to xxx sent (648 bytes)
03.12.2009, 18:11:04: SEND  - connection finished - 1 message(s) sent

i looked at the transfer with wireshark and found that after the initial TCP handshake the server sends a 220 response which is ACKed and then there is a 12 second pause until i see my side (the client) send an EHLO packet.  after that the transfer runs smoothly.

my question is: what is causing this 12 second delay?  how can i avoid it?

any help is appreciated.  i can be reached by mail as well as lueders and then this little round symbol and afterwards the domain of cfos.de.
