Hi, I have configured Logback SmtpAppender. I am receiving mails properly most of the times but sometimes instead of rendering HTML, the whole HTML source is in the email. I am using gmail. I have attached the discussion mail from logback-user mailing list below.
I will be highly obliged if you could provide some information on how I can resolve this. Thank you. Regards, Saurabh Khanduja. ---------- Forwarded message ---------- From: Saurabh Khanduja <khandujasaur...@gmail.com> Date: Sun, Sep 4, 2016 at 3:58 PM Subject: Re: [logback-user] Email sent by logback is sometimes corrupt To: logback users list <logback-u...@qos.ch> Hi David, I was able to trace the sender code to SMTPAppenderBase:374. Most probably the issue is how Multipart or Transport handles this message. Tried debugging further, but I am seriously new to this. This doesn't looks like configuration issue, but more like how mails should be fomatted. I googled about how to send mail for Multipart emails, and found: http://stackoverflow.com/questions/14744197/best-practices-sending-javamail- mime-multipart-emails-and-gmail http://stackoverflow.com/questions/13299155/how-do-i- send-an-html-email-with-javamail *http://stackoverflow.com/questions/5068827/how-do-i-send-an-html-email <http://stackoverflow.com/questions/5068827/how-do-i-send-an-html-email>* - This clearly says html content should not have head, body tags. *Problem: *I'm on Mac and using gmail. IMO google should not display textual mime part. I will be moving this to developers-mailing list. Thank you. *Code:* String contentType = layout.getContentType(); // This is set to HTMLLayout in my conf. if (ContentTypeUtil.isTextual(contentType)) { // This is true as content type is text/html part.setText(sbuf.toString(), charsetEncoding, ContentTypeUtil.getSubType(contentType)); } else { part.setContent(sbuf.toString(), layout.getContentType()); } Multipart mp = new MimeMultipart(); mp.addBodyPart(part); mimeMsg.setContent(mp); mimeMsg.setSentDate(new Date()); addInfo("About to send out SMTP message \"" + subjectStr + "\" to " + Arrays.toString(toAddressArray)); Transport.send(mimeMsg); Thank you.
