In reply to shameeksl. One option is to create a web page that allows users to reset their passwords, but you need to implement some sort of double authentication. Otherwise everyone can reset anyone's password by simply knowing their e-mail. It's not that easy, you have to implement a whole web mail type of program.

Thanks for this tutorial. But is it possible to enable end users to change their passwords?

Consider catch-all as a regular user that receives e-mail for non-existing users on @domain-one.com. As you can see there is no username in front of

@domain-one.com domain-one.com/catch-all/

So, if I send an email to asdfasdf@domain-one.com and there is no such user, it will end up in catch-all mailbox, therefore you have to create this user in dovecot.

Very useful tutorial. Thank you very much.
But I have one problem for retrieving catch-all email.
After setting the catch-all email like below, which user should i set in dovecot user to retrieve its mail?
@domain-one.com domain-one.com/catch-all/

It is simple. How many domains do you own and want postfix to be a mail server? Let’s say only one e.g. something.com.
How many users need email? Let’s say three e.g. user1, user2 and user3. In that case, create/edit this file (/etc/postfix/virtual_domains) and add the following line.

something.com

Edit or create /etc/postfix/vmailbox and add the following lines.

user1@something.com something.com/user1/
user2@something.com something.com/user2/
user3@something.com something.com/user3/

Send the password to klimenta@iandreev.com and I’ll take a look. I can’t guarantee that I’ll fix it though…BTW, I am using Digital Ocean VPS and all my posts are tested on CentOS 6.5 hosted there.

In reply to Kliment Andreev.

Sorry. I kida had given up :).
Here is a screen host. I did what you asked, first I didn’t have telnet, but I installed it. And still the same problem.

I know this is a big DONT DO, but I could give you my password to my VPS so you could take a look if you wanted too. Since I have nothing in it, and will be re-installing it again, it won’t be a problem.
Sorry for this whole mess. I just can’t find a clue of what the problem could be,
