Java Mail sending with attachments

[Deepan Ignatius]

Hi All,

I am using the below code part to send mails with attachments.

Properties props = new Properties();   
props.put("mail.smtp.host", host);   
props.put("mail.smtp.port", port);       
for (int i=0;i<Files.length;i++)   
{   
    try  
    {      
        javax.mail.Session session = javax.mail.Session.getDefaultInstance(props, null);   
        session.setDebug(debug);   
        MimeMessage msg = new MimeMessage(session);   
        msg.addHeader("ROWID_Value", "X0001");   
        msg.setSubject(subject);   
        msg.setFrom(new InternetAddress(fromAddress,fromName));   
        for(int j=0;j<to.length;j++){   
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to[j]));   
        }   
        MimeBodyPart mbp1 = new MimeBodyPart();   
        mbp1.setText(text);   
        Multipart mp = new MimeMultipart();   
        mp.addBodyPart(mbp1);   
        // create the second message part   
        MimeBodyPart mbp2 = new MimeBodyPart();   
        FileDataSource fds = new FileDataSource(Files[i]);   
        mbp2.setDataHandler(new DataHandler(fds));   
        //mbp2.setFileName(fds.getName());   
        mbp2.setFileName(MimeUtility.encodeText(fds.getName()));    
        // create the Multipart and add its parts to it           
        mp.addBodyPart(mbp2);   
        // add the Multipart to the message   
        msg.setContent(mp);   
        Transport.send(msg);   
    }   
    catch (SendFailedException sfe)   
    {   
        logger.error(sfe.toString());   
        logger.error("ICOMS_UI_ERROR_102_ICOMS-SMTP-CONNECTION-ERROR");   
        return false;   
    }   
    catch (Exception mex)   
    {   
        logger.error(mex.toString());   
        logger.error("ICOMS_UI_ERROR_102_ICOMS-SMTP-CONNECTION-ERROR");   
        return false;   
    }   
}

The above code works with files having size upto 6 MB. For files greater than 6 MB, I am getting the below exception thown at line number 31:

javax.mail.SendFailedException: Sending failed;
nested exception is:
class javax.mail.MessagingException: 552 #5.3.4 message size exceeds limit

Could you guys consider sorting out this issue?

Thanks>

Lots of mail servers reject attachments of X MB or bigger, for varying values of X. Anything larger than 3 MB is definitively not a good idea.

But by using the below unix command, I am able to send file with more than 10 MB also

/usr/bin/uuencode "filename" "filename" | mailx -s "subject" mailids

Are there any options in Java to overcome this?

Are you using the same mail host? Because it's not Java that's rejecting the message, it's the server. The exception message, "552 #5.3.4 message size exceeds limit", is a message that comes directly from the server; the 552 is the server's status code which basically means "Requested mail action aborted: exceeded storage allocation".

[Deepan Ignatius]

I am not sure of it. How to check the mailhost?

Also could you share with me the doc you are referencing to find in detail the exception meaning? Thanks!

The mailhost is what you're connecting to; for the Java code it's the content of the "host" variable. I have no idea what mailx uses, but it could use the local machine as an intermediate.
