>Description:
On a freshly installed FreeBSD 8.2-RELEASE running in a virtual machine, I cannot send mail to localhost, because sendmail always dies with signal 11.

I know that VirtualBox doesn't support FreeBSD as a guest, but I find strange that sendmail crashes while other executables work fine, and I could successfully build some ports.  If I run the same FreeBSD image in QEMU instead of VirtualBox, sendmail works.

as a non privileged user, issue the command:
$ echo test | mail myuser

myuser's mailbox doesn't change, and "dmesg" shows:
