Hello Remy,

The problem starts after >>SMPT Response: 354 Enter message, ending with
"." on a line by itself<<
On my PC I get in the next frame >>SMTP Message Body<< and the e-mail is
  sent

but on my clients PC I get the following frames:
124 seconds >>TCP 1284 > smtp [ACK] Seq=96 Ack=299 Win=65237 [TCP
CHECKSUM INCORRECT] lEN=0<<

After 7 seconds the following frame from source 00:1c:57:0a:c0:8b to
destination 00:1c:57:0a:c0:8b >>LOOP Reply<<

424 seconds >>SMTP Response: 421 mayrelay01.solcon.nl SMTP incoming data
timeout - closing connection.<<

Well, my Delphi application was waiting for 5 minutes in stead of 1 hour.
There ar no frames of >>SMTP Message Body<< in the list.

My client has a Cisco router.

Do you have any idea ?

Thanks,
Hubert
