That would be great if you could post your workaround!
Thanks

[appengine-java] Re: GAE 1.3.1 java.io.IOException: Truncated quoted printable data when processing a Hotmail email
I have a fix for this that i will share later this evening, but i also
ran into this issue. It would be good to have this fixed.
My fix basically entails parsing the native stream when i encounter
this error. There is an apache library which is doing the parsing. I
made a simple alteration to a piece of an apache quoted printable
parser to make it work and extracted this into a utility. Looks
something like
getContent(msg) {
try {
return msg.getContent();
} catch (e) {
return FixedQuotedPrintableParser.parse(msg.getNativeStream)
}
}
I'll post the real code when i get a chance.

[appengine-java] Re: GAE 1.3.1 java.io.IOException: Truncated quoted printable data when processing a Hotmail email
Something has gotten broken with recent release because my code used to work fine with Hotmail/Yahoo sent messages. Looks like I have to go through release notes for 1.3.1 and fix processing incoming emails.. :- ( On Mar 21, 11:48 pm, Lucian Baciu wrote: > The mail processing API doesn't seem to work when processing a Hotmail > email message.
