I would recommend that you reopen this bug, we experience problems
downloading an 36 mb attachment with a 128 mb memory limit.
With a 256 mb memory limit it is ok.

Running latest stable horde / imp and php.

It seems that allot of the memory is consumed by the str_replace calls
in lib/MIME/Contents.php -- One could wonder if a unix/windows line shift
conversion is really nessecery in a binary attachment, eg. zip file. - One
might also think it would be smarter streaming the attachment directly to
the client at download and not drag it through php memory?

I haven't looked much into this as other things take priority at the
moment, does anyone experience similar problems?
