I have a strange problem I cant seem to fix.
1[[:)]] SMTP Transparent Mode on, skip source/destination conatins entry for internal mail server (Exchange 2003) When like this emails are caught according to SMTP proxy filters, but some ESMTP commands are ripped out and telnet to the Exchange server does not allow certain things to work
2[[:)]] Transparent mode off, no email are caught by the SMTP proxy but the ESMTP commands work correctly.
this problem came about because we were trying to send emails to someone but they were not being delivered.
When trying to telnet these are the results ( i have written out the ip's and mail addresses
250 smtp.domain.com Hello x.x.x.x [x.x.x.x]
mail from:<>
250 OK
rcpt to:real.user@domain.com
550 No such user.
250 smtp.domain.com Hello x.x.x.x [x.x.x.x]
mail from[:P]ostmaster@domain1.com
250 OK
rcpt to:real.user@domain.com
250 Accepted
When transparent mode is off using the mail from:<> work correctly.
Can anybody help me with this?
