Hi Zhang,

In my case, I am using dynamic email accounts, so how I will use the dynamic email accounts here? How I pass the email address there?

Hi Zhang,

So it means for each dynamic email account, I must have to do entry in /etc/postfix/master.cf for that email account ? In my application, there may be thousand of email accounts can be created so is it advisable to do so many entry in master.cf? Please suggest.

Hi Zhang,

As I told you already that I am creating multiple dynamic email accounts. So, suppose if I have test1@mydomain.com and test2@mydomain.com then how I will do the entry in master.cf? As per Wikki, I have to do the following:-

sql> USE vmail;
sql> UPDATE mailbox SET transport='external-pipe' WHERE username='test1@mydomain.com';

sql> USE vmail;
sql> UPDATE mailbox SET transport='external-pipe' WHERE username='test2@mydomain.com';

and then how it will be in master.cf :-

external-pipe         unix    -       n               n               -               -       pipe
    flags=DRhu user=vmail:vmail argv=/path/to/your/external/script.sh -f ${sender} -d ${user}@${domain} -m ${extension}

Can anyone please explain? How I map it with multiple email accounts?

Hi Zhang,

Thanks for your response.

But still I am not clear about how I achieved this? As you told that in master.cf, I will set recipient@example.com. But my issue is that I have multiple email accounts like test1@example.com, test2@example.com, test3@example.com etc. and for each email account how I set the "-d ${user}@${domain} " option in master.cf file? My domain name is fixed but the user is not fixed as it is creating dynamically. It may be test1, test2, test3 or something so I will set this in master.cf file and also how my script file will identify that mail is coming on test1@example.com or test2@example.com or test3@example.com etc.?
