Hi Guys
I've been forced to talk securely to an Exchange box, using some dummy
domains the Exchange admin set up atm. I can send to it fine from my
exim-running linux box but when I try the other way round I get a 501 error:
1, erniePDC, -, 60, 0, 4, 0, 0, EHLO, -, erniepdc.ernie.mshome,

This is stupid IIS log format, which gives the most detail. I think the "+"s
stand for " ". Leastways, a successful non-TLS attempt looks similar:
<snip>
oldfield, OutboundConnectionCommand, 2/10/2003, 17:56:29, SMTPSVC1,
erniePDC, -, 20, 0, 4, 0, 0, MAIL, -,
FROM:<Administrator@???>+SIZE=580,
oldfield, OutboundConnectionResponse, 2/10/2003, 17:56:29, SMTPSVC1,
erniePDC, -, 20, 0, 6, 0, 0, -, -, 250+OK,
<snip>
So looks like the problem is when Exchange says:
MAIL FROM::<Administrator@???> SIZE=593
which is, afaik, syntactically valid under normal conditions. Anyone got any
ideas?
Cheers
John
