javamail - java mail api javax.mail.MessageException Connect failed pop3 -


i want read mails user account using java mail api.

the mail server particular mail server:

reademail.java - client 

properties props = system.getproperties(); props.put("mail.debug", "true"); props.put("mail.pop3.host", host); props.put("mail.pop3.port", port); props.put("mail.pop3.user", username); props.put("mail.pop3.timeout", "158000"); props.put("mail.pop3.connectiontimeout", "158000"); /*  create session , store read mail. */ session = session.getinstance(props); store = session.getstore("pop3"); session.setdebug(true); store.connect(host,username, password);

the error message on client side:

debug pop3: mail.pop3.apop.enable: false  debug pop3: mail.pop3.disablecapa: false debug pop3: connecting host "localhost", port 4444, isssl false s: +ok  mail server ready  c: capa s:  javax.mail.messagingexception: connect failed;   nested exception is:     java.io.ioexception: unexpected response:      @ com.sun.mail.pop3.pop3store.protocolconnect(pop3store.java:210)     @ javax.mail.service.connect(service.java:295)     @ javax.mail.service.connect(service.java:176)     @ com.mail.reader.mailreader.connect(mailreader.java:67)     @ com.mail.reader.testmailreader.main(testmailreader.java:21) caused by: java.io.ioexception: unexpected response:      @ com.sun.mail.pop3.protocol.readresponse(protocol.java:752)     @ com.sun.mail.pop3.protocol.multilinecommand(protocol.java:766)     @ com.sun.mail.pop3.protocol.capa(protocol.java:675)     @ com.sun.mail.pop3.protocol.<init>(protocol.java:140)     @ com.sun.mail.pop3.pop3store.getport(pop3store.java:261)     @ com.sun.mail.pop3.pop3store.protocolconnect(pop3store.java:206)     ... 4 more

given seems complain unexpected response capa, might mail server sends non-standard response. try setting mail.pop3.disablecapa true, won't send capa.

as aside system.getproperties(); returns shared properties object, not sure if that's intented. maybe new properties(); instead?
