Re: disabling SMTP

yes. there are a lot of pix firewalls out there with smtp fixup turned on,
effectively disabling ESMTP (not to mention sporadically breaking
traditional SMTP.)

Could you elaborate on this? I use PIX firewalls all over the place and don't seem to have a problem with SMTP or ESMTP.
