Besides dk's suggestion it might be a good idea to contakt the author of MIME::Entity.

Reading perldoc perlipc reveals this:

Internet Line Terminators

The Internet line terminator is "\015\012". Under ASCII variants of Unix, that could usually be written as "\r\n", but under other systems, "\r\n" might at times be "\015\015\012", "\012\012\015", or something completely different. The standards specify writing "\015\012" to be conformant (be strict in what you provide), but they also recommend accepting a lone "\012" on input (but be lenient in what you require).

We haven't always been very good about that in the code in this manpage, but unless you're on a Mac, you'll probably be ok.

So if MIME::Entity has hardcoded \n instead of \015\012, either there is some way to make sure \n spits out \015\012 and you haven't read the documentation fully (I haven't), or the author didn't know about the standard.
