I have a prospective EBay customer who wants me to ship a few small items to Mexico City. Is their mail system reliable? If I ship USPS, I know I won't be able to get a tracking number (like any international package), but I don't know how trustworthy their mail system is. My wife is a filipina and I know better than to try to send any package of value to her family in the Philippines via regular mail. Anyone have any experience with this?

Thank you....

I've got family outside Mexico City and I've never had any problem sending letters and the occasional package of small gifts (cd's, dvd's, packs of photos) through the USPS.

I know that DHL and UPS operate throughout the country, and those certainly would offer tracking numbers, so if you are concerned about delivery, perhaps you should check into using one of them.

I've sent USPS and FedEx to various places in Mexico and never had a problem.
