1. PHP compilation on FreeBSD-powerpc gives a ton of "signal 11" ... all caused by the entry in "extensions.ini": extension=odbc.so ..
remove this and php will work as advertised!
2.

1. Most likely it is the "size" parameters for Postfix that is the cause.....
Do a "postconf | grep -i size" and you'll probably see something like the following:

bounce_size_limit = 50000
header_size_limit = 102400
mailbox_size_limit = 51200000
message_size_limit = 51200000

raise these to something sensible(it is within the main.cf), and do a "postmap main.cf" restart postfix and you should be ready to go......

1. There is a problem with "wmnet" on netBSD... There is a reference in the "wmnet.c" file to the symbol "alloca" .. but there is no include file for this.....
Best fix right now is to "comment" "wmnet" in the Makefile the metapkg, as this is just for modems etc... so no worry!

If you have the problem that you cannot get logged in with "cyradm" when trying to create/access/whatever users....
Do notice.....(provided you have not established any other passwordroutines.......) that the "saslpasswd2" password have to be the same as the "passwd" password....
