Question:
We're using the activeX control and have a customer that can send 1 email, but when he tries a 2nd, receives the following error:
SendEmail: DllDate: May 8 2015 ChilkatVersion: 9.5.0.49 UnlockPrefix: RAYMONMAILQ Username: D4KDM9R1:George Architecture: Little Endian; 32-bit Language: ActiveX VerboseLogging: 0 sendEmailInner: renderToMime: createEmailForSending: xSigningAlg: sha1 Auto-generating Message-ID --createEmailForSending renderToMime: Elapsed time: 0 millisec --renderToMime sendMimeInner: progressTotal: 1434 ensureSmtpSession: ensureSmtpConnection: SmtpHost: smtp.onecommunications.net SmtpPort: 25 SmtpUsername: george.dawkins@binnewater.com SmtpSsl: 0 StartTLS: 0 smtpConnect: smtpHostname: smtp.onecommunications.net smtpPort: 25 connectionIsReady: Need new SMTP connection --connectionIsReady smtpSocketConnect: socketOptions: SO_SNDBUF: 262144 SO_RCVBUF: 4194304 TCP_NODELAY: 1 SO_KEEPALIVE: 1 --socketOptions --smtpSocketConnect smtpGreeting: readSmtpResponse: SmtpCmdResp: 220 *********************************** --readSmtpResponse --smtpGreeting ehloCommand: sendCmdToSmtp: SmtpCmdSent: EHLO D4KDM9R1<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 250-smtp005.earthlinkbusiness.com SmtpCmdResp: 250-PIPELINING SmtpCmdResp: 250 8BITMIME --readSmtpResponse --ehloCommand --smtpConnect --ensureSmtpConnection ensureSmtpAuthenticated: smtpAuthenticate: smtp_host: smtp.onecommunications.net smtp_port: 25 smtp_user: <<customer's user="" name="" that="" worked="" the="" first="" time=""> smtpAuthenticate: login_method: LOGIN auth_login: smtpSendGet2: sendCmdToSmtp: SmtpCmdSent: AUTH LOGIN<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 502 unimplemented (#5.5.1) --readSmtpResponse --smtpSendGet2 AUTH LOGIN failed --auth_login Failed to login using LOGIN method --smtpAuthenticate ConnectionType: Unencrypted TCP/IP --smtpAuthenticate --ensureSmtpAuthenticated --ensureSmtpSession --sendMimeInner --sendEmailInner Failed. --SendEmail --ChilkatLog
Please test first with the latest version of Chilkat (v9.5.0.52).
Also.. it's probably not a good idea to be doing SMTP over an unencrypted TCP connection (port 25) with the "LOGIN" authentication method, where the login and password can be clearly seen by anybody sniffing the network...
i had faced the same issue like above , i had tried with new dll which is relased on 26th aug 2015 ,version 9.5.0.52. can you tell what changes needs to be done .
In my particular case, I changed the port to 465 and enabled SSL and that worked for my client, even though his ISP said they didn't use SSL.
