Hi,
I'm a new user using stunnel-5.03 on Windows SBS 2003.
I can't send email from Exchange but can from Outlook with same credentials on same network.
Email gets stuck in the exchange smtp queue.
Simple config:
; * Global options
debug = 7 output = stunnel.log engine = capi options = NO_SSLv2
; * Service definition
[SMTP] client = yes accept = 8465 connect = smtp.virginmedia.com:465 protocol = smtp
Logs look good but nothing seems to go:

If I rem out the protocol = smtp then the mails go from the queue and the logs seem to indicate a success:

but all Mails bounce with:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <server.domain.local #5.5.0 smtp;530 Authentication Required (VM401)>
Any ideas?
