Delphi 5.
In the TIdSMTP.Connect method, in order to set the timeout to infinity, do I
use 0?
eg.
IdSMTP.Connect(0)
or
IdSMTP.Connect()?
However, looking into the source code of TIdSMTP.Connect, it does not use
this timeout parameter:
procedure TIdSMTP.Connect(const ATimeout: Integer = IdTimeoutDefault);
var
NameToSend : String;
begin
inherited;
try
GetResponse([220]);
FAuthSchemesSupported.Clear;
if Length(FHeloName)>0 then
NameToSend := FHeloName
else
NameToSend := LocalName;
if FUseEhlo and (SendCmd('EHLO ' + NameToSend )=250) then begin //APR:
user can prevent EHLO {Do not Localize}
GetAuthTypes;
end
else begin
SendCmd( 'HELO ' + NameToSend, 250 ); {Do not Localize}
end;
except
Disconnect;
Raise;
end;
end;

though as its just a guess. I am not that knowledgable with how indys
internals work - I just noticed the inherited bit which would explain what
you were looking for.
I'm sure Remy will be able to give you a better idea.
 

Further thoughts...
I'm sure Remy said a while back in another topic that the OS itself will
time out if a socket doesn't connect.
I think Indys timeout is just a timeout if the server doesn't acknowledge
the connection in a reasonable time - I think if the OS itself accepts the
connection the timeout doesn't work - Only if the server doesn't respond...
I'm probably wrong but thats a vague memory...

IdSMTP.Connect(IdTimeoutInfinite)
Specifying 0 is the same as specifying IdTimeoutDefault (which is what
Connect() defaults to). That causes Connect() is wait a maximum of 2
minutes when TIdAntiFreeze is used, or until the socket errors on its own.
TIdTCPClient.Connect(), which then passes it on to
TIdIOHandlerSocket.ConnectClient(), where it is actually used.

connect without erroring.
ignored. Any activity on the connection is subject to the ReadTimeout
property from that point on.
