WHM)

2025-03-29

Hi,

I would like to make SMTP service available on another port besides 25. The reason is that many ISPs block port 25 because of spam issues. So my customers can't send mail through the SMTP server they get access to along with hosting package. I know, they can use their ISP's SMTP, but for many of them this is not the real solution.

Anyone knows how to do it? Any help would be appreciated.

The server has CPanel/WHM with Exim.

Thanks
