Just a simple check to make sure that a person's email address matches their domain.

For example .. in a form you have 2 textboxs .. 1 for their website url, the other for their email address. This checks to see if the domains for the email address and the website url match.

Makes sure the email addresses with IP addresses are not private network addresses. Allows multiple sub-domain levels. verifies characters within domain names. only allows standard length 26 characters for each domain name level, except the top (3 max)

This script allows the creation of an Outlook Distribution List from a text file. This is handy for creating a quick email distribution list without having to manually add each contact to the list.

I have used it only a couple times, but was born out of a need from a listserv member - they use it almost daily for emailing contacts pulled from a terminal-windowed application and saved as standard output.

Maybe you'll find this useful, maybe not, but thought I'd share it...

Send an email with VB.net 2.0 with your SMTP Serve

This perl subroutine uses the CPAN module Mail::Webmail::Gmail to iterate through a Gmail account searching for a particular string. If a match is found, the sender's name along with his/her email address, the subject, and the "blurb" is printed to standard out. Also, all messages found will be archived automatically within Gmail to clear the message from the inbox folder. The subroutine returns the number of messages found back to the calling environment.

Sample invocation: check_email(username, password);

By default, the subroutine will use encryption to connect to Gmail however, by setting encrypt_session to '0' will disable encryption.
