hello all.



Please suggest, Does this helps? if asked the Exchange admin of jandbindustrial.com to do the below 



Set-RemoteDomain –TNEFEnabled $false –identity ‘RemoteDomainName’


That’s all. RTF e-mails should be converted to text format before it sends to the application server. No more winmail.dat attachments.

I have modified few option in mailscanner.config file .  apart from it I  whitelisted this domain.


Deliver Unparsable TNEF = yes, by default it was set to no, I set it "yes"

TNEF Expander = /usr/bin/tnef --maxsize=1000000000 (increased the size bit)

# The maximum length of time the TNEF Expander is allowed to run for 1 message.

# (in seconds)

TNEF Timeout = 240 ( it was set to 120 now I make it 240)



Any help  on the above would be greatly appreciated.

True - but remember some braindead M-Sexchange admins will forcibly turn RTF/TNEF on at the server level. Seen it happen.

Can you get the sender to try a different mail client, i would lean
towards TNEF causing the issue if they are sending via outlook or such,
so a quick test would be to get them to try a different mail client. or
make sure they switch to html/plain emails
