Like another user on here, I cannot receive email. I think it maybe a seperate issue though, because the mail is being delivered into the file, but UebiMiau locks up and wont let me in! I have setup a VPS server using the Perfect Debian 3.1 setup. Then installed ISPConfig. I have DNS configured for one domain at Everydns.net to point to my server. I created a site and a user, and from that user, sent an email to my standard gmail email address, which I received. I responded from there to test receiving email. Now when I try to login to UebiMiau it locks up for like a minute and I eventually get an error: "Login error - You cannot login with the username and password entered. Please check your username and password and try again." I am using the same username and password which worked the first time! I tried it with two seperate accounts and confirmed UebiMiau locks a user out up as soon as an email is received for a user. Mail is being put into /var/mail/web1_sbecker. The email is making it to the server, because I can see it in the file! But it seems that as soon as something is in the inbox, I can no longer login to UebiMiau. Here are the last few lines of my /var/log/mail.log Code: Mar 23 23:34:47 server1 ipop3d: Mailbox vulnerable - directory /var/mail must have 1777 protection Mar 23 23:34:47 server1 ipop3d: Login user=web1_sbecker host=vps [127.0.0.1] nmsgs=2/2 Mar 23 23:34:47 server1 ipop3d: Command stream end of file while reading line user=web1_sbecker host=vps [127.0.0.1] Mar 23 23:39:49 server1 ipop3d: Mailbox vulnerable - directory /var/mail must have 1777 protection Mar 23 23:49:06 server1 ipop3d: pop3 service init from 127.0.0.1 Mar 23 23:54:08 server1 ipop3d: Mailbox vulnerable - directory /var/mail must have 1777 protection Mar 23 23:54:08 server1 ipop3d: Login user=web1_sbecker host=vps [127.0.0.1] nmsgs=2/2 Mar 23 23:54:08 server1 ipop3d: Command stream end of file while reading line user=web1_sbecker host=vps [127.0.0.1] Mar 23 23:59:10 server1 ipop3d: Mailbox vulnerable - directory /var/mail must have 1777 protection netstat -tap output: Code: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:imaps *:* LISTEN 6524/inetd tcp 0 0 *:pop3s *:* LISTEN 6524/inetd tcp 0 0 vps:mysql *:* LISTEN 12800/mysqld tcp 0 0 *:pop3 *:* LISTEN 6524/inetd tcp 0 0 *:imap2 *:* LISTEN 6524/inetd tcp 0 0 *:www *:* LISTEN 8137/apache2 tcp 0 0 *:81 *:* LISTEN 8103/ispconfig_http tcp 0 0 *:ftp *:* LISTEN 8904/proftpd: (acce tcp 0 0 server1.electroi:domain *:* LISTEN 8267/named tcp 0 0 vps:domain *:* LISTEN 8267/named tcp 0 0 *:ssh *:* LISTEN 4088/sshd tcp 0 0 *:smtp *:* LISTEN 11051/master tcp 0 0 vps:953 *:* LISTEN 8267/named tcp 0 0 *:https *:* LISTEN 8137/apache2 tcp 0 52 server1.electrointe:ssh 148-103.35-65.tamp:3511 ESTABLISHED10305/0 my /etc/postfix/main.cf (domain changed to xyz.net) Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h myhostname = server1.xyz.net alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname #mydestination = server1.xyz.net, localhost.xyz.net, , localhost relayhost = mynetworks = 127.0.0.0/8 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names Here are my ISPConfig email settings: MTA Type: Postfix Virtuser File: /etc/postfix/virtusertable Sendmail CW: /etc/postfix/local-host-names Mail Log: /var/log/mail.log Save Log: No Maildir: No Antivirus-Admin: admispconfig@localhost Spamfilter: Yes Also, I did not install Courier-IMAP/Courier-POP3, should I have done this?
