I'm facing a very weird problem :
the platform i'm installing has three different domains : N1, N2 and
N3. Each domain contains a client and a server running windows server
2003.
N1 and N2 use IIS POP3/SMTP built-in functionality, N3 uses a
shareware POP/SMTP server (mdaemon). The dns (hosted by N1) is
properly configured.
I manage to send these mails :
client_N3 -> client_N1
client_N1 -> client_N3
client_N3 -> client_N2
client_N2 -> client_N3
but i CAN'T send :
client_N1 -> client_N2
client_N2 -> client_N1
In other words, i can't send mail between two hosts using IIS
POP3/SMTP built-in functionality.
A deeper analysis with ethereal, in the case client_N1 -> client_N2,
shows that mx dns request is solved, that an smtp transfer between
servers is initiated (a long long time after mail reception by N1
server, which is much faster in the case client_N1 -> client_N3 for
instance) but that the smtp session ends a strange way (sometime a
timeout occurs, sometime a quit command isn't sent after a bdat
command ...)
If anyone can help me solving this silly problem ...
