Dear all, I am trying to send out an SMTP email using the "mailman" but I keep getting a socket timeout in the process: SendEmail: DllDate: Mar 6 2015 ChilkatVersion: 9.5.0.48 UnlockPrefix: GUDFINMAILQ Username: GKRPROD01:SYSTEM 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: 5355 ensureSmtpSession: ensureSmtpConnection: SmtpHost: mail.axelero.hu SmtpPort: 25 SmtpUsername: gkristj SmtpSsl: 0 StartTLS: 0 smtpConnect: smtpHostname: mail.axelero.hu smtpPort: 25 connectionIsReady: Need new SMTP connection --connectionIsReady smtpSocketConnect: socketOptions: SO_SNDBUF: 262144 SO_RCVBUF: 4194304 TCP_NODELAY: 1 --socketOptions --smtpSocketConnect smtpGreeting: readSmtpResponse: SmtpCmdResp: 220 mail01d.mail.t-online.hu ESMTP You must authenticate before sending mail --readSmtpResponse --smtpGreeting ehloCommand: sendCmdToSmtp: SmtpCmdSent: EHLO GKRPROD01<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 250-mail01d.mail.t-online.hu SmtpCmdResp: 250-PIPELINING SmtpCmdResp: 250-SIZE 26214400 SmtpCmdResp: 250-VRFY SmtpCmdResp: 250-ETRN SmtpCmdResp: 250-STARTTLS SmtpCmdResp: 250-AUTH PLAIN LOGIN SmtpCmdResp: 250-AUTH=PLAIN LOGIN SmtpCmdResp: 250-ENHANCEDSTATUSCODES SmtpCmdResp: 250-8BITMIME SmtpCmdResp: 250 DSN --readSmtpResponse --ehloCommand --smtpConnect --ensureSmtpConnection ensureSmtpAuthenticated: smtpAuthenticate: smtp_host: mail.axelero.hu smtp_port: 25 smtp_user: gkristj smtpAuthenticate: login_method: LOGIN auth_login: smtpSendGet2: sendCmdToSmtp: SmtpCmdSent: AUTH LOGIN<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 334 VXNlcm5hbWU6 --readSmtpResponse --smtpSendGet2 sendCmdToSmtp: SmtpCmdSent: Z2tyaXN0ag==<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 334 UGFzc3dvcmQ6 --readSmtpResponse sendCmdToSmtp: SmtpCmdSent: {PasswordOrCredentials} --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 235 2.7.0 Authentication successful --readSmtpResponse --auth_login --smtpAuthenticate ConnectionType: Unencrypted TCP/IP --smtpAuthenticate --ensureSmtpAuthenticated --ensureSmtpSession sendSmtpEmail: sendWithPipelining: sendMailFrom: mailFrom: admin@thehuntinglounge.com sendCmdToSmtp: SmtpCmdSent: MAIL FROM:<admin@thehuntinglounge.com><crlf> --sendCmdToSmtp --sendMailFrom sendRcptTo: sendCmdToSmtp: SmtpCmdSent: RCPT TO:<gudfinnur@gkr2004.com><crlf> --sendCmdToSmtp --sendRcptTo sendCmdToSmtp: SmtpCmdSent: DATA<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 354 Ready, steady, go --readSmtpResponse readRcptTo: readSmtpResponse: SmtpCmdResp: 250 2.1.0 Ok --readSmtpResponse recipient: gudfinnur@gkr2004.com --readRcptTo readSmtpResponse: SmtpCmdResp: 250 2.1.5 Ok --readSmtpResponse smtpRset: Sending RSET command. smtpSendGet2: sendCmdToSmtp: SmtpCmdSent: RSET<crlf> --sendCmdToSmtp readSmtpResponse: recvUntilMatch: Socket operation timeout. --readSmtpResponse --smtpSendGet2 --smtpRset --sendWithPipelining --sendSmtpEmail --sendMimeInner --sendEmailInner Failed. --SendEmail --ChilkatLogEverything seems ok, until it is time to send out the actual body of the email. Any ideas? Thanks, Gudfinnur Kristjansson |
Your SMTP server seems to be responding to each pipelined command in reverse order. For example, if I send email via smtp.gmail.com, it works as it should: sendWithPipelining: sendMailFrom: mailFrom: chilkat.support@gmail.com sendCmdToSmtp: SmtpCmdSent: MAIL FROM:<chilkat.support@gmail.com><crlf> --sendCmdToSmtp --sendMailFrom sendRcptTo: sendCmdToSmtp: SmtpCmdSent: RCPT TO:<admin@chilkatsoft.com><crlf> --sendCmdToSmtp --sendRcptTo sendCmdToSmtp: SmtpCmdSent: DATA<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 250 2.1.0 OK i80sm5219011iod.6 - gsmtp --readSmtpResponse readRcptTo: readSmtpResponse: SmtpCmdResp: 250 2.1.5 OK i80sm5219011iod.6 - gsmtp --readSmtpResponse recipient: admin@chilkatsoft.com --readRcptTo readSmtpResponse: SmtpCmdResp: 354 Go ahead i80sm5219011iod.6 - gsmtp --readSmtpResponse --sendWithPipelining mimeDataSize: 347 sendDataToSmtp: numBytesSent: 347 --sendDataToSmtp sendCmdToSmtp: SmtpCmdSent: <crlf>.<crlf> --sendCmdToSmtp readSmtpResponse: SmtpCmdResp: 250 2.0.0 OK 1429223498 i80sm5219011iod.6 - gsmtp --readSmtpResponse --sendSmtpEmail In both your case and mine, the order of commands is: MAIL FROM The responses SHOULD be in this order: 250 (The 354 is the success response code for the DATA command) Your SMTP server sends responses in reverse order: 354 Your SMTP server indicates it's doing pipelining, but it seems to be behaving incorrectly. I'll be adding a new property to explicitly turn off the pipelining feature in v9.5.0.49 |
Thanks for the quick response. Yes, it all works fine in my development environment (HMailserver) but when I deploy to production (third party SMTP server), this problem comes up. I'll be waiting for v9.5.0.49. Gudfinnur Kristjansson |
Thanks! I'll have a look. I think it must have to do with SMTP pipelining. It's likely I won't have a further response until tomorrow..
