This is somewhat OT here but worth mentioning in any case, I think: at the beginning of the internet era, e-mail communiction was reliable. How/why? Messages that did not get through to the intended recipients would cause the mail system to send a notice of non-delivery to the sender, and people using e-mail knew what to do with those non-delivery notices.
But things have changed. MOST e-mail messages being sent noawadays are spam: as I've learned from various related technical reports over the years, related estimates commonly lie well over 90% (spam, that is), and a rather large percentage of e-mail - mostly spam but also a certain amount of legitimate mail - remains undelivered as a result of spam countermeasures. Next, many contempodary mail systems do no even generate non-delivery notices any more (there are reasons for this) and some systems send them only selectively, based on the origin or type of the messages that turned out undelivered. And then, of those mail messages that ARE delivered (reach the intended recipients' computers) many are discarded there by automatic filters that the users have set up or that their software uses automatically.
That's the technical end of it. Add to that the human element: even though there are still some non-delivery notices being sent, and even though some of those make it through to the intended recipients, most people have no idea what to do about those messages and don't follow up on them. There are other potential problems with users, but I think we can disregard those in this context.
What is the upshot of all of this? As you have just found out yourself, relying on e-mail to communicate with people with whom you don't have an established connection already (that is a connection that has proven to work) can be a hit-or-miss affair with more misses than hits.
Is there anything that can be done about this? My own solution (of which I don't know to what extent it might apply to others) is this: if i send a message/attachment to someone and want to be sure that it reaches its destination i call the recipients and confirm whether or not they have received what i sent them and whether they are able to process it (on the odd occasion a message/attachment may have been received but cannot be opened). If I am expecting someone else's important email i call them after a few minutes/hours/days (depending on the urgency and other circumstances) to confirm whether they have sent what they were going to send. In cases where things don't work out to my satisfaction i repeat the abovementioned process, switch to a different communication method, or replace my communication partner - whichever serves my purpose...
And you've apparently solved the problem you experienced by posting to Forumosa - i won't argue with success.
