Integration of winmail.dat attachments

[Chachou41]

Sometimes outlook users send attachments "winmail.dat" which are attached as is in mantis, and hardly usable.

This extension allow conversion from winmail.dat to originals files (png, pdf, whatever)

Dependency on linux utilitary "tnef", to install separately.
No impact if "tnef" not provided does nothing

I'm assuming you're using a Microsoft Exchange server. Why not just disable TNEF for the EmailReporting mailbox or the whole exchange server?
Microsoft Exchange will then do a full conversion of winmail.dat when necessary.
It's old but might help: https://capsulecrm.com/support/setup-and-configuration/microsoft-tnef/

[Chachou41]

The EmailReporting mailbox is not on Exchange Server, only some users send reports from Exchange, and we don't necessarily have control over their email client configurations.

So we implemented this workaround in the EmailReporting code we've been using for several years.

[SL-Gundam]

Ah yes. So bad configuration on other mail servers causing issues for you.
I will go through the code and let you know.

[SL-Gundam]

It looks good. Couple things that need improving though.
If you don't want to improve the code since in its current state it works for you then it might be better to move it into a separate MantisBT plugin that monitors EmailReporting or MantisBT events and work on that data.

Probably better to do this with native PHP code, rather than calling an external executable.

Maybe https://github.com/QualityUnit/TNEFDecoder could be used for this.

I think you're right @dregad. Thank you for the idea.

The necessary changes have been made to the EmailReporting Experimental branch

QualityUnit/TNEFDecoder added to Composer: 92da731

@Chachou41 Would you be willing to test this once this has been released (hopefully next week). I'm afraid i did not have any emails on hand with winmail.dat attachments so testing was limited and based on loose winmail.dat files.
