Double quoted local parts failing syntax tests?

I am working with the pysrs library and have been doing some testing and
when i give it a _legal_ (albeit rarely if ever used) email address of
"Blah blah"@blah.com to forward encode it creates something like:

SRS0=uPbPNkV0=TC=blah.com="Blah blah"@adomain.com

However this address when placed into an envelope from command gets
syntax errors. Is this specifically a problem with the Python library
or SRS in general?

Thanks,
David

That would be a problem with the python library. I will add a test case.
What *should* the answer be? I think it should be:

"SRS0=uPbPNkV0=TC=blah.com=Blah blah"@adomain.com

I checked rfc2822, and

"SRS0=uPbPNkV0=TC=blah"."com=Blah blah"@adomain.com

is also allowed! But I think we'll stick with the first form. :-)

Please check that the required result is correct.

Thanks for the reply Stuart. A couple other things that ought to be
checked in conjunction with this:
1) That the form "SRS0=uPbPNkV0=TC=blah.com=Blah blah"@adomain.com can
be properly be re-forwarded by other SRS sender libraries
2) That the form "SRS0=uPbPNkV0=TC=blah.com=Blah blah"@adomain.com can
be properly be reversed to "Blah blah"@blah.com by the current SRS libraries

Thanks,
David

Test cases already check reforwarding and reversing.

The fixed code is checked into CVS. Give it a try if you could.
Only SRS/Base.py and testSRS.py were touched.

Confirmed it works. Do you know if the other libraries (ie perl, C,
etc) behave in the same fashion and can re-forward and decode this form
of address (given the proper secret, etc)?

Thanks,
David
