We have set up a mailserver on DirectAdmin on CentOs years ago and worked fine, but now my ISP has blocked all my access (due to alleged abuse) except for transport to their own smtp server.
But in my mailqueue there are several mails which are send by my customers and need to be delivered somewhere.
I get the notice from my ISP that I have to deliver them on their smtp server via a SSL or SMTP authentication.

How do I set that up in DirectAdmin, or do I need to do that in de CentOS?

In your mail client you can enable 'verification required for sending by SMTP'.
Also you could try port 587 instead of 25 for outgoing email with SMTP.
 
I understand mail client

I understand that I can change the mailclient. but all my clients have send their mail already and it is in my mailqueue on the DA box. How do I get the mail queue to deliver to that smtp server?
 
You can login at DirectAdmin (admin) and go to Mailqueue administration.
Then select all mail and press 'retry'.
 
But if there is a block, it still won't go. Doesn't matter how many times I retry. The mail needs another way out....
 
Then let the customers resend the email from their own ISP.
You can only send the email at your server FROM your server, not from someone else unless you have another server for mail relay.
 
I have another smtp server to which the mail in my queue may go. is that possible for mail that is already in the queue?
 
I'm trying to understand this thread. When you write about your ISP are you writing about the ISP which hosts your mailserver? If so, only your ISP can unblock port 25, and port 25 is required for you to send email from your server. Well, not quite, if you have another server elsewhere you can set up your server to use a smarthost through another port, but you'll need to find the details yourself as it's not a supported configuration. Search for smarthost on these forums or ask on the exim-users mailing list.

If this isn't what you mean, then please explain further.

the port 25 is blocked, except for the smtp relay server from my ISP. I will look into the smarthost solution. thank you.

With this I think you are having problems with your ISP (Internet Service Provider) where you have internet from at home. Only they will block port 25.

Hosting companies where you can get a dedicated, colocation or whatever normally don't block port 25. And also since you got the email already at the server I don't think its a problem about port 25.

Is the server at a datacenter, or on a static IP# from your ISP (home or office)?
