I have server where I want to set up a mail server to let me receive and send email from my domain. I’m currently having a problem where while I am can not receive mails. Sending emails works perfect.

I’m going off of this script, which shows how to configure a mail server using Postfix, Dovecot, and using Postgresql as the backend (https://gist.github.com/solusipse/7ed8e1da104baaee3f05).

/etc/postfix/main.cf:

    relay_domains =
    virtual_alias_maps = proxy:pgsql:/etc/postfix/virtual_alias_maps.cf
    virtual_mailbox_domains = proxy:pgsql:/etc/postfix/virtual_mailbox_domains.cf
    virtual_mailbox_maps = proxy:pgsql:/etc/postfix/virtual_mailbox_maps.cf
    virtual_mailbox_base = /home/vmail
    virtual_mailbox_limit = 512000000
    virtual_minimum_uid = 5000
    virtual_transport = virtual
    virtual_uid_maps = static:5000
    virtual_gid_maps = static:5000
    local_transport = virtual
    local_recipient_maps = 
    transport_maps = hash:/etc/postfix/transport

    smtpd_sasl_auth_enable = yes
    smtpd_sasl_type = dovecot
    smtpd_sasl_path = private/auth
    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
    smtpd_sasl_security_options = noanonymous
    smtpd_sasl_tls_security_options = 
    smtpd_tls_auth_only = yes
    smtpd_tls_cert_file = /etc/ssl/private/server.crt
    smtpd_tls_key_file = /etc/ssl/private/server.key
    smtpd_sasl_local_domain = 
    broken_sasl_auth_clients = yes
    smtpd_tls_loglevel = 1
    html_directory = /usr/share/doc/postfix/html
    queue_directory = /var/spool/postfix
    mydestination = localhost

/etc/dovecot/dovecot.conf:

    protocols = imap
    auth_mechanisms = plain
    passdb {
        driver = sql
        args = /etc/dovecot/dovecot-sql.conf
    }
    userdb {
        driver = sql
        args = /etc/dovecot/dovecot-sql.conf
    }
    service auth {
        unix_listener /var/spool/postfix/private/auth {
        group = postfix
        mode = 0660
        user = postfix
        }
        user = root
    }
    mail_home = /home/vmail/%d/%u
    mail_location = maildir:~
    ssl_cert = </etc/ssl/private/server.crt
    ssl_key = </etc/ssl/private/server.key
