Hi list!
I'm trying to run postfix on my OpenWrt system. I have successfully
compiled it and now I can send mails, but when I try to receive a
mail, smtpd crashes and I can see this in the system log:

This happens every time I receive a mail.
I also tried to telnet to the smtp port and found out that postfix
correctly responds to HELO and crashes right after I send MAIL
command.
Besides that, the whole system is very stable, so I don't believe it
is a hardware fault.
