How to setup correctly Exim4

How to setup Exim4 in order to get a mail server and be able to send email through CMS scripts, like Wordpress, Vbulletin, phpBB, etc... First install the Exim4 package on your linux distribution :

sudo apt-get -y install exim4

Apply

dpkg-reconfigure exim4-config

Then configure Exim 4 :

– Mail sent by smarthost; received via SMTP or fetchmail
– Type System Mail Name: yourdomainname.com
– Type IP Adresses to listen on for incoming SMTP connections: 127.0.0.1
– Leave Other destinations for which mail is accepted blank : yourdomainname.com
– Leave Machines to relay mail for: blank
-Type Machine handling outgoing mail for this host (smarthost): smtp.gmail.com::587
– Hide local mail name in outgoing mail : NO
– Keep number of DNS-queries minimal (Dial-on-Demand) : NO
– Mbox
– Split configuration into small files : NO

After that :

nano /etc/exim4/exim4.conf.template

Find the line .ifdef DCconfig_smarthost DCconfig_satellite and add this part just after :

send_via_gmail:

driver = manualroute

domains = ! +local_domains

transport = gmail_smtp

route_list = * smtp.gmail.com

Remove the next domains = ! +local_domains, i.e. smarthost :

    #smarthost:

    #  debug_print = "R: smarthost for $local_part@$domain"

    #  driver = manualroute

    #  domains = ! +local_domains

    #  transport = remote_smtp_smarthost

    #  route_list = * DCsmarthost byname

    #  host_find_failed = defer

    #  same_domain_copy_routing = yes

    #  no_more

Find begin authenticators, and after this add :

gmail_login:

driver = plaintext

public_name = LOGIN

client_send = : yourname@gmail.com : YourGmailPassword

You have to set of course your gmail email address and to add your gmail email account password.

Find transport/30_exim4-config_remote_smtp_smarthost, and after that add :

gmail_smtp:

driver = smtp

port = 587

hosts_require_auth = $host_address

hosts_require_tls = $host_address

Remove the end of the file :

#.ifndef AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS

    #  client_send = "<; ${if !eq{$tls_cipher}{}\

    #                    {^${extract{1}{:}{PASSWDLINE}}\

    #        ^${sg{PASSWDLINE}{\\N([^:]+:)(.*)\\N}{\\$2}}\

    #      }fail}"

    #.else

    #  client_send = "<; ^${extract{1}{:}{PASSWDLINE}}\

    #       ^${sg{PASSWDLINE}{\\N([^:]+:)(.*)\\N}{\\$2}}"

    #.endif



    #login:

    #  driver = plaintext

    #  public_name = LOGIN



    #.ifndef AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS

      # Return empty string if not non-TLS AND looking up $host in passwd-file

      # yields a non-empty string; fail otherwise.

    #  client_send = "<; ${if and{\

    #                          {!eq{$tls_cipher}{}}\

    #                          {!eq{PASSWDLINE}{}}\

    #                         }\

    #                      {}fail}\

    #                 ; ${extract{1}{::}{PASSWDLINE}}\

    #    ; ${sg{PASSWDLINE}{\\N([^:]+:)(.*)\\N}{\\$2}}"

    #.else

      # Return empty string if looking up $host in passwd-file yields a

      # non-empty string; fail otherwise.

    #  client_send = "<; ${if !eq{PASSWDLINE}{}\

    #                      {}fail}\

    #                 ; ${extract{1}{::}{PASSWDLINE}}\

    #    ; ${sg{PASSWDLINE}{\\N([^:]+:)(.*)\\N}{\\$2}}"

    #.endif
