May I begin with saying I am very beginner with this issue, and have been searching for hours to try and fix this.

I am trying to setup a mailserver using Squirrel Mail, Docevot and Postfix.

I have gotten to the point where I can get to the squirrel mail login, but I keep getting this error...

Dec 19 16:24:59 vps647603 dovecot: imap(sales): Error: open(/var/mail/sales) failed: Permission denied (euid=1005(sales) egid=1005(sales) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0775) Dec 19 16:24:59 vps647603 dovecot: imap(sales): Error: Failed to autocreate mailbox INBOX: Internal error occurred. Refer to server log for more information. [2019-12-19 16:24:59]

The results of 'postconf -n' and 'dovecot -n' are below if this helps..

root@vps647603:~# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all inet_protocols = all mailbox_size_limit = 0 mydestination = mattemedia.co.uk, vps647603.ovh.net, localhost.ovh.net, localhost myhostname = vps647603.ovh.net mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes

root@vps647603:~# dovecot -n

2.2.9: /etc/dovecot/dovecot.conf

OS: Linux 3.13.0-167-generic x86_64 Ubuntu 14.04.6 LTS

mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap pop3" ssl_cert =

Any help would be extremely appreciated, and may I apologise in advance for my lack of knowledge.

Many thanks

  • Running a web server is easy; running a mail server is not. If the reason of your exercise should be not to learn about how to operate such a thing and instead is to have a system ready for you in production use, then you are far better suited with a specialized setup like Mailcow (https://mailcow.email), which comes preconfigured with all the internal bells and whistles. Also note that Squirrel Mail is horribly outdated, and unmaintained. You should try Roundcube or Horde Webmail instead. – Marc Stürmer Dec 22 '19 at 22:43

Dovecot is lacking write permissions in directory /var/mail/sales and the error message is thus quite clear.

This command will add the user to the 'mail' group:

adduser sales mail
