I've just borrowed the code myself for a new ICS HTTP proxy component that will be in SVN in a week or so.

Re: [twsocket] SSL enabling SMTPCLi
Hello, I shortly looked at the mentioned sample. It contains some pem files which seem to be certificates. Correct? The seem to be different from the ones I already used for my DataSnap rest server to SSL enable it. And the other thing: if I initiate some SMTP connection using such certificates, will the server validate them agains some URL? if yes how? Or can I distribute generic certificates along with my application andn they should work? Then there's the difference between StartTLS and the "normal" method. Can the client automatically detect which one to use? I don't like the user requiring to set up so many parameters... that could go wrong :-( Regards Markus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] SSL enabling SMTPCLi
Hello Angus, thanks for your answer. It is a good starting point for me once I actually find the time to do the necessary changes (which is not now). As for sending issues: I already implemented the possibility to specify several e-mail servers in my application which will be tried in the specified order if one should not be reachable. That looks good enough for now. But rest assured: I use your component for using dial up networking, if specified by the user, since years already. I just don't know if any user actually uses it as the e-mail finctionality is only used by a subset of the user base. Back when implementing this I did test it, but at work it's difficult nowdays to find an analogue phone port and a working modem ;-) (back when testing it it first failed and after fixing some implementation bugs on my side I finally learned that the modem I had lent was defective as well ;-) So I lent a different one from IT department which worked ;-) ) Best regards Markus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

> Sending still works, but only for SMTP servers not requiring TLS. > What would I need to do to TLS enable this application? Look at the sample OverbyteIcsSslMailSnd, which is the SSL enabled version. Essentially, you change to use TSslSmtpCli which has extra events to handle the SSL handshaking events, and add an SslContext which controls the SSL negotiation. Or you could change it to use my Mail Queue Component, which already handles SSL, queues and retries email with multiple servers over 24 hours so it has a higher chance of being sent. https://www.magsys.co.uk/delphi/magics.asp > My application meanwhile provides some webservice as well using > the built in DataSnap technology of Delphi, which also means I > already distribute the 2 SSL DLLs required for this ICS always uses the latest OpenSSL 1.1.0 released a year ago, Indy is stuck with an older version that uses different file names, so you will have to distribute four DLLs with your application. ICS will use the older 1.0.2 versions as well, but I would not recommend it.

[twsocket] SSL enabling SMTPCLi
Hello, I once wrote a Delphi application in D2007 sending e-mails via SMTPCli which got migrated to Berlin 10.1 meanwhile and thus ICS got upgraded to some 8.x version. Sending still works, but only for SMTP servers not requiring TLS. What would I need to do to TLS enable this application? There surely is some demo available for this, but I'd like to assess the amount of time/complexity this task might require. My application meanwhile provides some webservice as well using the built in DataSnap technology of Delphi, which also means I already distribute the 2 SSL DLLs required for this (I once updated them with newer versions from the fulgran server). Would TLS enabling SMTPCli interfere with those (by requiring some DLLs with the same name but differently compiled or something like this)?
