| Author | Forum: PowerTCP Mail for .NET Topic: SMTP with TLS (Smtp.Security = Security.Explicit) |

posted June 2, 2008 8:46 PM I'm trying to send using the SMTP object in SecureMail v1.0.5.0. I'm using MS Exchange 2007 set to use TLS. I've set the following for the security fields... Smtp.Security = Security.Explicit; Smtp.UseAuthentication = false; The log is as follows. To my eye, it looks like a connection is being made and it's even accepting the STARTTLS command, but it breaks down after that. Does anyone know what the problem could be? If this is a problem that we can't get around with configuration, is this something addressed in the latest version of the software? EHLO <servername> 250-<blablabla> Hello [<ip>] 250-SIZE 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-AUTH NTLM 250-8BITMIME 250-BINARYMIME 250 CHUNKING STARTTLS 220 2.0.0 SMTP server ready MAIL FROM:<blablabla> SIZE=138 RET=HDRS RCPT TO:<blablabla> ORCPT=rfc822;<blablabla> DATA 503 5.5.2 Send hello first QUIT |

posted June 6, 2008 7:00 AM I've downloaded the trial for v3.0.3.2, and using the included SMTP Client (VS2005, synchronous) sample, I'm still able to reproduce the problem as before. Is there something else I need to do? |

posted June 6, 2008 5:30 PM Hi, I have taken a look at the code, and it looks as though the issue was fixed for non-Pipelining servers only. I have re-opened the issue, and it will be addressed for Pipelining servers in the next release. For updates on the status of the issue, please contact Jamie Powell (support@dart.com). I apologize for the inaccuracy of my previous response. -ken ------ |

posted June 9, 2008 4:59 PM Any idea when that might be? This, in my estimation, is one of the most common configurations for Microsoft Exchange... |

posted June 9, 2008 5:33 PM Hi, You can contact Jamie Powell (support@dart.com) for questions about the status of the issue. As far as the configuration being common, it depends on what you mean. Yes, Pipelining is common. But SMTP servers that use SSL are actually extremely uncommon. -ken ------ |
