I have an Ubuntu server running at a remote location which I log into with putty My dynamic ip is maintained using a NoIP account.
I am trying to learn about php dynamic websites and as a result I also connect to this remote server using core ftp and an ftp connection from a copy of Dreamweaver Studio8.
It's taken a while but I appear to have e-mail working from a "telnet local host 25" and now my web page contact appears to be working.
However when I looked at my mail queue using mailq I have four refused e-mails from the dynamic assigned IP.
When I followed this up I found the IP was sometimes blocked by Spamhaus PBL and investigation suggested I set up a smarthost through my isp but the server is on one isp and my home account and target for my mail is another so which isp do I use?
The infuriating thing is at most the out going e-mail will go to one of three addresses and even then only one at any one time I would realy like to be able to say this Domain name with associated ip address can mail to this e-mail adddress so that this cannot be hijacked by spammers.
So a second question is if this is possible how do I do this?
