Hi,
I am facing issue while sending SMIME from java application. struggling from past 1 week - very urgent.
Issue description :
1. From java application I am creating SMIME and sending mail through outlook change server domain to receiver(xxx@yyy.net) in other domain.
To connect to receiver below details provided to SMTP:
SMTP host : outlook change server domain
From:radhika@myorganization.com
To : xxx@yyy.net
With these setting I was able to send signed MIME to client properly up to past 1 week successfully. Client application also able to receive and parse SMIME.
2. Client reporting now, received MIME is not a signed SMIME.
As per logs provide by client, SMIME(content-type :multipart/signed) send by java application is wrapped with content-type :multipart/mixed under that content-type: message/rfc822 under that content-type :multipart/signed.
3. Client application always expects content-type :multipart/signed, if any other type receives client application will rejects that message.
4. As per internet sources, suspecting, SMIME is wrapped with footer/header by exchange server.
Not able understand why exchange server suddenly appending header/footer to SMIME?
is header/footer (content-type :multipart/mixed) added by exchange server?
How can I send 'content-type :multipart/signed' to receiver? Client application accept only 'content-type :multipart/signed'
Please help me to solve this issue.
Thanks you!
Radhika
