Use client's own SMTP

[itwanabe]

Clients are getting a lot of their mails being sent directly into spam folders (hotmail, yahoo, gmail). I had to work real hard to get those companies to recognized my emails (domains) and not bounce them. They filter it directly into their user's spam folder, a step forwards IMO...

But is there a possibility to use user's own SMTP for their domain (bright house, comcast, etc). I know they can use it if they setup on outlook for an example... But all my users use webmail directly from the server.

I have searched high and low (google and here) and found nothing. Can someone point me to the right direction? (i'm thinking this might need custom coding like a plugin of some sort). Thanks

Do you want to move MX records on them? Or do you want exim to send emails through them?

@zEitEr:

What user itwanabe wants to do is have squirrelmail send email through his clients' ISP's own mail server.

@itwanabe:

While I hate to say anything is impossible, this is going to be harder than figuring out why your email isn't getting to hotmail, yahoo, gmail, etc., from your own server. Much harder, because you're going to have the same problem with each ISP of each of your users. Since most of them accept email for relay only from inside their own networks, and since your server isn't inside the network of each ISP, with most of them, getting their cooperation will be anywhere from extremely difficult to impossible.
