I'll jump in on this one as I've been bitten by the small /var more than once! Watch out for /tmp too as the the local mail delivery agent called by sendmail (usually rmail) will write into /tmp. So if you are trying to deliver a large file it may still fail, and even if you have the space in /var/mail. I create my systems without a physical /var parition and symlink /var and /tmp into /usr/var and /usr/tmp respectively, this eliminates all problems, and you don't end up "wasting" lots of disk space for temporary files. Can we make this the default of sysinstall? Alternatively you CAN create a biggish /var partion and link /tmp into /var/tmp.
