Email exist verification

Hi Is it possible to check if an email-address is existing? I have earlier heard that it was possible through "contacting" the email-host, but it could be "dangerous" because your domain could be banned by the respective email-host an treated as spam.

Protecting email addresses on HTML pages from email spiders

How do you prevent emails being gathered from HTML pages by email spiders? Does mailto: linking them increase the likelihood of them being picked up? I think I read somewhere about a built-in Ruby function that confuses email spiders by decimal-encoding the email address - can anyone link me to some documentation or tell me how effective...

PHP mail filtering script: exit codes not recognized in .qmail file

Short story I've got a PHP script filtering incoming mail using a .qmail file. The script works perfectly well and logs all activity but, as far as I know, the last .qmail line shouldn't be executed when my script returns a dot-qmail exit code 99 that should stop processing further .qmail lines.

Blocking Spoofed Form Entries

We have a registration form where people can sign up to take surveys for a small compensation. Recently we found a lot of suspect entries. I tracked down a site in Chinese that I translated via google and it was basically a "how to" to sign up for these sorts of sites. I've been working to track down a way to automatically filter off the...

Text vs html emails

Our site generates several emails per day, a lot of which can contain awkward links, such as http://company/process/task?id=1234-4123-2352-1234&amp;user=xyz... Consequently I have been sending text only emails, on the suspicion that they will be treated more 'fairly' by email filters along the way. I cannot afford to lose emails to clie...
