I have a problem with the communication support. Maybe you can help me with this. I have correctly installed the template and entered all the parameters correctly. But whenever I press the email button, I get the error message which I have uploaded in the picture. What's wrong thank you for helping Walter ![image](https://clarionhub.com/images/transparent.png) ---

Hi Walter, the smtp-implementation in Clarion is useless since TLS \> 1.1 is mandantory on almost every well configured smtp-server. The Communication-Support even nowadays in Clarion V11 is not able to support TLS 1.2 and so no mail sending can be done with clarion. A pain in the ass. Before 2018 it was no problem at all! You may find some add ons, some external expensive tools like mail.dll or better use calls via run to Outlook or Thunderbird. If you re interested in further details on sending with external Mail clients, fell free to let me know. best regards from Hamburg, Germany Ralph Rathmann ---

I thought I’d heard that there was an updated ClaRunEx DLL that you could get from support@softvelocity, with updated TLS. But I might not be remembering correctly. ---

Hello Ralph, The following is some code I have using Mike Douglas’s LibCur that works against Microsoft servers correctly. I hope this can help you. ```auto ! send_mail(),long send_mail procedure()!,long curl TCurlMailClass res CURLcode is_ok long i long strTo cstring(255) add_to long code is_ok = true curl.Init() curl.Server( gMail.server, gMail.port ) curl.Account( gMail.user, gMail.passwd ) curl.From( sFrom ) add_to = 0 strTo = '' !message(sTo) loop i = 0 to 9 strTo = ItemS( sTo, i, ' ,;' ) if clip(strTo) <> '' curl.AddRecipient( strTo ) !to/cc/bcc !message( strTo ) add_to = add_to + 1 else break end !* if * end !* loop * curl.UseSSL( CURLUSESSL_ALL ) curl.SetSSLVerifyPeer( false ) !curl --insecure curl.Subject( _subject ) curl.Body( _body ) curl.AddAttachment( _attach ) curl.SetOpt( CURLOPT_CONNECTTIMEOUT, 45 ) !connection timeout (seconds) res = curl.Send() if res = CURLE_OK sStatus = 'Mail enviado correctamente.' else sStatus = curl.StrError(res) is_ok = false end !* if * return is_ok !* end * ``` ---

Hi Gustavo, thank you, this looks very interesting and i will this give a try at first.

Hallo Walter. Ich verwende aufgrund des TLS-Zeugs seit Jahren “einfach” NetTalk,
