The final edit in the /etc/postfix/main.cf file is related to the settings needed for Postfix to use the external SMTP server. The settings instruct Postfix to deliver emails via a relay host, which is an external SMTP server.

Find and update the following line of the configuration file as follows:

relayhost = [SMTP-SERVER-ADDRESS]:587

• Replace SMTP-SERVER-ADDRESS with the SMTP server IP address or hostname.

Add the following lines to the end of the file:

smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

Save the changes and exit the editor.

Anyway, to build it:

Grab the procmail-wrapper.c from the virtual-server module directory, or from:

http://software.virtualmin.com/lib/procmail-wrapper.c

Build it with:

gcc -o procmail-wrapper procmail-wrapper.c

Assuming you’ve got gcc installed. setuid the resulting binary and put it in place instead of the binary you have now.

Another alternative is to run Sendmail instead of Postfix. Sendmail already calls procmail using a setuid wrapper (at least, it does on most platforms). I don’t necessarily recommend it, as I don’t like Sendmail configuration and find it unnecessarily terse in error loggin, but Virtualmin supports it just fine and once setup either mail server acts roughly identically.

Other method :

The fix is:

cd /root
wget https://github.com/virtualmin/virtualmin-gpl/blob/master/procmail-wrapper.c
gcc procmail-wrapper.c -o procmail-wrapper
mv /usr/bin/procmail-wrapper /usr/bin/procmail-wrapper.backup
cp procmail-wrapper /usr/bin/procmail-wrapper
chmod 4755 /usr/bin/procmail-wrapper

If you don’t do the 4755 you’ll get weird Procmail errors and SpamAssassin won’t work.

Try to go to the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters. If not already there, create a new REG_DWORD value named IPEnableRouter. Set IPEnableRouter to 1 and reboot. Packet forwarding should now be enabled.

To add static routes use the route command.

POP3

Incoming mail sever : mail.domain.com / port 110 / no encryption

Outgoing mail server : mail.domain.com / port 587 / no encryption

Setingan di atas mestinya bisa untuk semua versi Outlook.

• Settingan lain yg mungkin hanya bisa untuk Outlook versi baru :

POP3

Incoming mail sever : mail.domain.com / port 995 / SSL encryption

Outgoing mail server : mail.domain.com / port 465 / SSL encryption

atau

Outgoing mail server : mail.domain.com / port 587 / TLS encryption

• Kalau settingan di HP android yg versi baru :

Incoming mail sever : mail.domain.com

Outgoing mail server : mail.domain.com

untuk port dan excryption nya tinggal pilih saja di menunya (semua bisa) dan biasanya menggunakan IMAP (karena keterbatasan memory penyimpanan di hp)
