Hi All, We are using James 2.3.2 in our production and started to see some issues for one of the customer who is using SMTP feature to send email to James and this email will be stored on local disk. Customer is using Zimbra mail server.
We understand James 2.3.2 very old version and is out of support. But if anyone is still using James 2.3.2 and can help us on error that we are can see in James logs. Recently we found this conversation where Noel J. Bergman had offered to help on any issue on 2.3.2. please find the link below. https://www.mail-archive.com/server-dev@james.apache.org/msg70615.html Exception we see in James logs: 08/07/21 14:41:21 ERROR smtpserver-tls: Unknown error occurred while processing DATA. javax.mail.MessagingException: Error in input stream; nested exception is: java.net.ProtocolException: pre-mature end of data at javax.mail.internet.InternetHeaders.load(InternetHeaders.java:365) at org.apache.james.core.MailHeaders.<init>(MailHeaders.java:61) at org.apache.james.smtpserver.DataCmdHandler.doDATA(DataCmdHandler.java:131) at org.apache.james.smtpserver.DataCmdHandler.onCommand(DataCmdHandler.java:81) at org.apache.james.smtpserver.SMTPHandler.handleConnection(SMTPHandler.java:393) at org.apache.james.util.connection.ServerConnection$ClientConnectionRunner.run(ServerConnection.java:432) at org.apache.excalibur.thread.impl.ExecutableRunnable.execute(ExecutableRunnable.java:55) at org.apache.excalibur.thread.impl.WorkerThread.run(WorkerThread.java:116) Caused by: java.net.ProtocolException: pre-mature end of data at org.apache.james.util.CharTerminatedInputStream.read(CharTerminatedInputStream.java:103) at org.apache.james.util.watchdog.BytesReadResetInputStream.read(BytesReadResetInputStream.java:98) at org.apache.james.util.DotStuffingInputStream.read(DotStuffingInputStream.java:50) at com.sun.mail.util.LineInputStream.readLine(LineInputStream.java:88) at javax.mail.internet.InternetHeaders.load(InternetHeaders.java:342) ... 7 more We have also found following code snippet from CharTerminatedInputStream.java which says the same. if (b == -1) { //End of stream reached without seeing the terminator throw new java.net.ProtocolException("pre-mature end of data"); } We suspect that this error is thrown when there is no termination is sent by the email data and end of stream is reached. We also observer for some of the email transfer, after the DATA command is issued we also see RESET command in the middle of data transfer after which there is no data received from mail server, is this normal behaviour ? This issue is intermittent and does not happen for every email. We also cannot identify for which email transfer this error is thrown. We feel this issue may be due to some network related issue from Zimbra server which is failing to send full data to James server. Is our understanding correct here ? Any help will be really appreciated. Thanks & Regards, Anup DISCLAIMER ========== This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
