我试图运行与“maildir”function和qpopper作为pop3服务器的后缀，我卡住了。
当我禁用“Maildir”function时，popper运行正常，但我想使它与MailDir一起工作。
我也试过很多maildir这样的名字：MailDir，mbox等等…
即使我有服务器上的电子邮件，pop3返回…
+OK someone has 0 visible messages (0 hidden) in 0 octets. popper使用xinetd运行。
/etc/xinetd.d # cat qpopper # # qpopper - pop3 mail daemon # service pop3 { port = 110 socket_type = stream protocol = tcp wait = no user = root server = /usr/sbin/popper server_args = -s flags = IPv4 }
而后缀configuration是：
queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/lib/postfix data_directory = /var/lib/postfix mail_owner = postfix unknown_local_recipient_reject_code = 550 mynetworks = 192.168.0.0/16, 127.0.0.0/8 home_mailbox = mbox/ debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail newaliases_path = /usr/bin/newaliases mailq_path = /usr/bin/mailq setgid_group = maildrop html_directory = /usr/share/doc/packages/postfix-doc/html manpage_directory = /usr/share/man sample_directory = /usr/share/doc/packages/postfix-doc/samples readme_directory = /usr/share/doc/packages/postfix-doc/README_FILES inet_protocols = all smtp_dns_resolver_options = res_defnames smtpd_banner = $myhostname biff = no mail_spool_directory = /var/mail canonical_maps = hash:/etc/postfix/canonical virtual_alias_maps = hash:/etc/postfix/virtual virtual_alias_domains = hash:/etc/postfix/virtual relocated_maps = hash:/etc/postfix/relocated transport_maps = hash:/etc/postfix/transport sender_canonical_maps = hash:/etc/postfix/sender_canonical masquerade_exceptions = root masquerade_classes = envelope_sender, header_sender, header_recipient myhostname = xxx.xxx.xxx delay_warning_time = 1h message_strip_characters = \0
谢谢！
我想你可能需要使用不同的POP3服务器，如Courier或Dovecot。
我无法在网上find有关popper支持除基本单一文件格式之外的任何信息。 事实上，我正努力寻找远程最近的文档或软件的来源…
QPopper不支持maildir。 此外，它不再维护，不应该再使用。 其他更好的select存在（例如鸽舍）。
