Connecting to imap server with one username and another email?

[Qualphey]

This kind of connection works on thundermail, so I suppose there should be a way to do the same thing with this module. Though there is only the user property in the configuration object. Any suggestions? :)

I'm not quite sure what your email client is doing. IMAP authentication almost always involves a username and some kind of password.

I think you didn't really get me right. I meant connecting to IMAP server using an email, username and a password.
ie:

{
  user: "foo",
  email: "bar@domain.com",
  password: "123456879"
}

But it's okay now. I've reconfigured my server to use postgresql database for user authentication instead of pam.

That's what I meant. I've never seen an email address be used as part of the authentication.

Well the email address is not used for authentication. It's used to specify which emails you want to fetch when you're using aliases and save these emails for multiple addresses at the same maildir that's located in the home directory of a user you authenticate with. I'm using Postfix and Dovecot. You can read more about Postfix vitual aliases here.

Since I'm not familiar with that kind of setup, there's not much I can tell you other than I'm confident it must be already possible with this module since all common IMAP functionality is available, it's just a matter of figuring out how Dovecot or other IMAP servers are making those email addresses available/selectable via IMAP.
