No, sorry, I won't kill my machines by letting PHP eat all of memory. Having
ocassional problems with memory limit is much more safe solution for this
problem. We only have X machines with only Y GB of RAM, and last time we
upgraded RAM (and memory limits) shortly after upgrade to IMP4, guess why.
That time I found out that 50MB is enough...

at least you know about this problem... and I hope you looked at other
php-based webmail products (squirrelmail?), if/how they solve this problem

Of course. I didn't want to insult horde/imp coders, just to comment current
status.
