I personally haven't noticed this problem (but that must not mean that it doesn't exist). BTW: smtpQuit just sends command Quit to the server. OnSessionClosed will be triggered later when the _server_ closes the connection. However Abort plus posting a custom message should work. Providing a simple test project that reproduces the error might help. A tester should be able to get that running within 5 minutes max. Just upload the test project to a website and post the link here. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html > > - I use OnRequestDone to start new session > - I don't use Application->ProcessMessages > - I only call Smtp->Abort in case of TimeOut. > - I use SmtpCli->Quit to terminate connection > > I notice it almost always happens after bad SmtpCli->Connect attempt: > > I receive SmtpRequestDone with error 10044 (Interrupted System Call), > then i PostMessage to initiate new Session, after receiving message by > my messages Handler i call SmtpCli->Connect for next session and > receive "Smtp component not ready". > > Please note: it's NOT happens after EACH 10004 error !
