RE: Asynchronous message queue by SMTP&POP3
There are numerous issues related to e-mail based transport of business documents (X12, XML or other): ?SMTP mail messages can travel unpredictably from Internet hosts.?* ?SMTP providers can only guarantee levels of service from end to end when the Internet Service Provider owns the entire transmission path.?* ?The sender then has no guarantee that expired messages will not be viewed.? * Lack of Access Controls allows hackers and spammers access to E-C Servers Many viruses travel by E-mail Known file size limitations Known problems with gateways on signed/encrypted messages No real-time acknowledgement *http://www.disa.org/x12/x12c/smtpedi.htm If you're looking for "business grade" transports look at EDIINT AS2, it's a HTTP based protocol.

Yes, I agree with you that they are standardized. And as you've mentioned, sending it is especially easy. There is no need of "custom" one. Things are basically the same with receiver side. If there exists a good POP3 component (with source), maybe I don't need a "custom" one, because I can imagine only few XML-specific functionalities But the problem is, I still cannot find such a POP3 component. And if I implement it from the scratch, it could have a better interface by sticking to the concept of "queue by e-mail". Is there something wrong with this reasoning? ---------------------- K.Kawaguchi Swift,Inc. E-Mail:k-kawa@s...
