True, but the default maximum individual header size is about 5Kb.
I run into this problem often enough (usually due to someone sending an
email to their entire address book), that I make it a habit to always
remove this limit on my courier installations.
I don't have a patch, but it's only a one line change.
Edit courier/submit.C and change this line:
if (l > headerlimit || l > 5000)
to this:
if (l > headerlimit)
And then rebuild the rpms.
Note - The original line shown above came from memory as I don't have
the unmodified source handy. It may not be exactly right, but if you
open the file and search for "headerlimit", you should find it on the
second match.
