I'm using idSMTP, and the host address as 25.
To test the performance I'm emailing to myself. The message seems to be
posted ok, but never arrives on the mail server (Xtra - this is NZ). There
are no errors.
I am using whatever version of Indy came with D6. XP has the firewall
enabled. I've checked the firewall log and there does not appear to be any
problems with it.
Can anyone come up with any ideas of anything else I may need to look for?
Thanks

Whoops - my mistake. The PORT is 25. The host address is
"SMTP.xtra.co.nz".
I recommend v9 as it is pretty much stable, however v 10 is the latest.
Whatever you decide to upgrade to, get the snapshot - not an old version as
they are all buggy.

Have you checked your POP3 inbox to see if the messages are being bounced
back to you separately?

Then you are using Indy 8, which is outdated and no longer supported.

Yes, nothing there. In fact I tested an Outlook email by addressing it to
myself. Outlook wouldn't send it. Which is strange because earlier
versions certainly used to. It's just that it's years since I've done
anything with sockets.

I figured that. Problem is I really don't need to use Indy for very much, at
this point, other than emailing. Installing later versions appears to be a
quite major operation. And fraught with the possibility of busting D6.
Right now I can't afford the down time.

Then they have gone into the abyss. If the SMTP server did not report any
errors, then you are guaranteed that it accepted the message data and its
delivery it now out of your hands. If you are not seeing the message
bounced back via POP3, then either:
1) your SMTP server delivered it successfully and the problem in on the
receiver's end
2) your SMTP server has simply not delvered the message yet, such as if it
is queued for later processing
3) your SMTP server is having problems delivering the message, but has not
given up on it yet. Most servers try for a few days before reporting a
failure back to the original sender.

Why not? What did it say?

Well, but there has been a lot of work done on Indy's emailing code over the
years, though. More so to support anti-spamming systems then to address
actual transmission issues. But there had been work done on TIdMessage's
support code as well for better message parsing and generating.

Upgrading from 8 to 9 should be less painful than upgrading from 8 to 10.

Nothing at all. I turned the network sniffer on to see if there was
traffic. There was. But the message didn't leave my PC.
I did send a message to someone else. That arrived. I can only conclude
the POP3 server is "bouncing" the message if you send it to yourself. So
goodbye to that method of testing. It looks like I'm just going to have to
bug other folks when testing SMTP connections.
Thanks for your help.

What exactly did you see?

How do you know for sure?

Not likely. I have never had problems sending emails to myself using any
ISP I have ever had. Besides that, POP3 has nothing to do with sending
messages. It is only for downloading them from the server after they have
been delivered successfully. If a message bounces, you would receive it via
POP3 (or IMAP, depending on your ISP settings), but the bounce itself is
still handled at the SMTP level.

You need to test this from a server installation of SMTP which hosts your
domain or from an email account of an ISP who hosts your domain.
I host my own domains on my own server but I could not get an email account
in Australia which would send email unless THEY hosted my domain.

I attempted to send a message to myself using Outlook. It never left the
outbox.
Very strange. Never run into that before. I used to test connections by
emailing myself. Now it doesn't seem to work. At least with my ISP. I did
succeed in emailing a friend using Indy components. So it works.
