[javamail-dev] Attached PDF issues

["Mike Andrasak" <andrasak@xxxxxxxxxx>]

I have 2 different
servers, one running javamail 1.5.2 and one running 1.6.2. The same application
is running on both. When an email is sent from the 1.5.2 server with a
PDF attached the receiving email address receives the email with the PDF
properly named and attached. When an email is sent from the 1.6.2 server
the email contains a .dat file attached instead of the .pdf attached. The
SMTP server for both applications is the same and the receiving email server
is Microsoft Outlook (it was verified that the following --> https://www.lifewire.com/prevent-sending-winmail-dat-attachments-1173717does not apply). pcapng traces were done with each version with the following
results seeming interesting. Note that the 1.6.2 version split the PDF
file name up. Looking for some additional direction to help determine what
the issue might be.

1.5.2:
Content-Type:
application/octet-stream; 
name="C:\\CIS\\Invoices\\Automated
 Invoices-FY19\\2019_07\\Invoices_0719-123.pdf"
Content-Transfer-Encoding:
base64
Content-Disposition:
attachment; 
filename="C:\\CIS\\Invoices\\Automated
 Invoices-FY19\\2019_07\\Invoices_0719-123.pdf"


1.6.2:
Content-Type:
application/octet-stream; 
name*0="C:\\CIS\\Invoices\\Automated
 Invoices-FY19\\2019_07\\Invoices_071";
name*1=9-116.pdf

Thanks!
