this really is quite odd, it should work. As far as I know Exchange SMTP
shouldn't worry about whether it gets CR or CR/LF.
In ESM, servers/sbs/protocols/smtp properties enable logging. This will give
you basic SMTP logging and should give you some idea. You can also enable
another form of logging in the properties for the server itself.
As Javier points out elsewhere, SBS using port 25 for it's SMTP server has
nothing to do with the problem as the connection is made from AS400:>1024 ->
remote:25. The fact you can't telnet to a remote:25 from the AS400 suggests
NAT is not working but this doesn't explain why the telnet to SBS:25 is not
working.
AS400 has only one interface/IP, right? It should have a command equivalent
to 'ipconfig /all', the output from this may help.
In the telnet session to SBS:25, there's no garbling of information or
missing characters in the responses from SBS, is there? /clutches straw.
