I have a terminal server where that we use for sales, inventory, purchasing, etc. Very often, we have to send emails (PDF invoices, purchase order, etc) which go out using postfix on this particular server. When we send these documents, we have to copy ourselves in order to have a record that it when out. It comes in to our Inbox. If we do not copy ourselves, we have no record of it going out. We have a separate IMAP server (main email server) that when I send email from my iphone, it will show up in the sent box on my computer. Is there a way to send these messages using postfix so that they are put in our sent folder of our Imap server without having to copy ourselves? Thanks.

@ Mau MAU , USE PHP.INI . create an account named postmaster@localhost . So php scripts send emails with postmaster account. Life is simple . Remember this. Hahahahaha.

So, if I am using this smtp relay how do I target the specific mapped account from say PHP?

Sorry if this is kind of a stupid question, but while I get how the config and everything is working I just don't know how to make the PHP script trigger one of the defined relay accounts.

Hi,

I think I know my mistake:
Here it is on main.cf
——————————————————————————————————————————————
smtp_sender_dependent_authentication = yes
sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_map
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd <– changed to = hash:/etc/postfix/passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes
——————————————————————————————————————————————

Then run the following commands:

sudo postmap hash:/etc/postfix/passwd
sudo postmap hash:/etc/postfix/relayhost_map
sudo /etc/init.d/postfix reload

By the way, it's very nice article thanks a lot.

Rgds,

Here are my configuration:

myhostname = ubserver.revetech.local
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = revetech.local, ubserver.revetech.local, localhost.localdomain, localhost
relayhost = [smtp.gmail.com]:587

smtp_sender_dependent_authentication = yes
sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_map
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes

And here is the content of the relayhost_map and /etc/postfix/passwd

nprasetio@ubserver:~$ sudo cat /etc/postfix/relayhost_map
prasetionico@gmail.com [smtp.gmail.com]
g00rkha75@gmail.com [smtp.gmail.com]

nprasetio@ubserver:~$ sudo cat /etc/postfix/passwd
prasetionico@gmail.com prasetionico@gmail.com xxxxxxxx
g00rkha75@gmail.com g00rkha75:xxxxxxxxx

Really appreciate your help.
