Glad you got it working.
I worked for some time for a mass mailing company.
From that experience I assure you that delivering mail is NOT easy.
Meanwhile, there are a lot of safety mechanisms installed on all "big" mail
platforms, and getting a mail delivered becomes more and more difficult.
Well, after a few more tests two of my test recipients again did not receive the
emails. Both are handled by GMail (of course). Now the reason is that GMail
determined that the recipient had gotten too many "similar" emails so it stopped
accepting them.
And I also saw that it is getting suspicious of the "non-validated" sender...
All of this is a PITA since I am working on porting an automatic environment
monitoring system from Delphi to FreePascal and Linux. Here the results will be
emailed packaged in a zipfile several times a day to a few recipients and it is
not acceptable that the recipient's mail server blocks these emails.
Welcome to the world of mailing.
I wish I could say it gets better, but it does not.
The body of the message is fixed at the moment, I could add a timestamp string
to it but not much more to make it "new" every time.
... :(
It might be better not to mail this, but to upload results to a server using
http, which puts everything in a database, and make a small frontend for your
database.
Michael.
