Could you tell me if Indy is useful por the following tasks, that I have
to implement in a Delphi application:
1) dial-up the remote provider in synch mode (the call should be
automatic, without any human intervention)
2) compose and post messages (I think it does this).

If YES (to the first question, mainly), which examples can I look at?
I have tried with other components, but they have problems with dial-up.
Thank you.

Indy does not manage links - the OS should do this. Windows seems to be
very poor at managing links, however. If, for example, you have a host that
is reachable by LAN and also, much slower, by dial-up, Windows occasionally
decides to dial up for no aparrent reason.

If you have a host that is unreachable by 'permanent' links, Windows should
dial up if there is a dial-up available that might allow reachability. You
can turn on dial-on-demand, but I've seen some odd thigs happen.

The only 'always works' dial-up method I've found is to use a RAS dial
component & explicitly dial from your application. I use the Async Pro
dialler. Don't try to use this in asynch mode though - very buggy &
freezeworthy. In sync mode in a thread, it works fine. I use it for
emailing from an app - no problems.

Oh, forgot to say. Once the dial-up connection is established, I use Indy
TidSMTP and TidMessage to send the mails. Works OK.
