SMTP Server answers 250 (OK) but Chilkat sometimes fails

Apr 28 '15 at 09:35

Hi all, hope someone has an idea about this topic. I'm using Chilkat ActiveX, version 9.3.2 with VB6. When I send mails from a Recordset of Recipients, most works fine, but for single Recipient-Adresses Chilkat returns an error allthough the SMTP-Server (MS-Exchange) returns the code 250 (OK). The sendmail-Command returns "SmtpCmdResp: 250 2.1.5 Recipient OK 250 2.1.5 Recipient OK Failed when sending DATA command smtpConversation: Elapsed time: 0 millisec Failed."

Sending the same Mails in a second try, everything is fine.

Is this maybe a bug, which is resolved in Chilkat, version 9.5? Can I use my unlockcode, which I got for Version 9.3.2 for version 9.5 also?

Thanks and regards Axel


Yes, you may use your old unlock code in v9.5. I would recommend giving it a test.
