I've happily installed MailScanner 4.66.5-3 (http://mailscanner.info) on FC8!
From a minimal FC8 server installation, I needed to install a few rpms using yum:
# yum install rpm-build
# yum install perl-devel
# yum install perl-Test-Simple
Since perl-Test-Simple is included with MailScanner, it might be possible to remove the requirement for that (and save having yum trying to update it) if it's listed earlier in the MailScanner install.sh?
Had an odd problem recently, in that my local hosts file wasn't being used to resolve domain names.
Much Googling later I found this thread, which prompted me to try editing the hosts file using edit from the windows command prompt. It worked, and now my hosts file is being used again!
A simple "Contact" form on a website. The form allows people to enter their name and e-mail address, so that the message appears to come from them, and the site owner can use their Reply button to reply to the sender (and not the web server!).
The problem is defining what the "sender" e-mail address is, which is then compared with the address's domain's SPF record to see if it is coming from an authorised mail server.
Some ISP's "hijack" port 25, so that all mail sent goes through their mail servers. This allows them to be sure that their internet connections are not being used to send spam.
Use port 587 for sending e-mail using the Fonant mail server to avoid this.
