Leamar, What do the smtp-queues look like? Are they filling up with unsend mail? If so, you could try if you can telnet on Port 25 through the isa... If the queus are empty than the email must dissappear somewhere and this somewhere should then be the ISA Server I guess. If you can't telnet through the ISA than you have a problem with some of your ISA rules (try www.isafaq.org, i guess the problem will be described there also). Succes!
