Found an even easier solution:
Reading the IMAP specification I noticed one can use mail_fetchbody()
with an empty section specifier ("") to retrieve the whole mail,
including headers. Downloading the message this way makes the Gmail
IMAP server transmit the whole message, untruncated. Now I can even
skip mail_fetchheader() and just use mail_fetchbody(). Two flies with
one stone.

If automobiles had followed the same development cycle as the
computer, a Rolls-Royce would today cost $100, get a million miles per
gallon, and explode once a year, killing everyone inside.
