[courier-users] Re: Maximum of 20 nested SPF queries exceeded.

Okay.

I changed the source, recompiled and ran some tests using telnet on another
server. It's my opinion the return value for "Maximum of 20 nested SPF
queries exceeded." in ./rfc1035/spf.c should be changed from SPF_FAIL to
SPF_UNKNOWN as this would match the /* comments */ above that code.


Before change (using telnet) Courier gives up completely:

helo malexmedia.net
mail from:<courier-mta-test@malexmedia.net>

517 SPF fail courier-mta-test@malexmedia.net: Maximum of 20 nested SPF
queries exceeded.


After change (in mail headers) Courier still gives up, but does not fail
the SPF:

Received-SPF: unknown (Maximum of 20 nested SPF queries exceeded.)
SPF=MAILFROM;
sender=courier-mta-test@malexmedia.net;
remoteip=::ffff:127.0.0.1;
remotehost=localhost;
helo=hi;
receiver=server;

I should also note that I tested this using courier-0.53.3.
