Check email addresses

With this feature you can validate all email addresses. If an address is not valid any more it can be deleted. SuperMailer uses syntax checking and/or DNS lookup (convert hostname to IP address). It checks all MX entries (Mail Exchange) for this entry, to get the valid email server and validates the email addresses.

validate how-to

1. Select recipients via email recipients within the SuperMailer main window. Now click on "Check email addresses" under menu Project.
   
   
2. Select "Only syntax checking" to check the syntax of email addresses.
3. Select "Syntax checking, check the server is reachable and email address exists on server" if you want to check the syntax of the email address and after then connect to the email server of recipient to verify the email address.
4. Not for syntax checking: Insert your DNS server, so SuperMailer can check his MX-entries.
   SuperMailer tries to find out a default DNS server of your system configuration. Only if this fails you have to insert a DNS server name by hand.
   If you use any kind of dial in connection, first of all connect to your provider and then start email address check, because only with an active internet connection SuperMailer can automatically detect your DNS server.
   
   
5. Not for syntax checking: Define the number of threads (parallel channels), you can use maximal 100 threads. Please note that a high number of threads results in a high system load. On systems running Windows 9x/ME more than 16 threads can cause system crash's.
   
   
6. Click on "Check now" to start this procedure.
   
   
7. After validation has finished, you get a list of all addresses, every address with a negative validation is marked. You can mark further email addresses by hand. Click on "Delete selected emails", to delete all marked email addresses from you list of recipients.

Problems during validation

• If the mail server of a recipient is temporarily not available, then this email address gets a negative validation.
• If MX entries are not defined correctly on an mail server, all emails registered to this server will be marked as not valid. At the same time this user can not receive any emails.
• Some Provider doesn't support this validation, in this case you will get an error messages "Relaying denied" and it is not possible to determine if this email address is correct or not. Otherwise some provider completely ignores such request and defines every given email address as correct or incorrect.
• You can only validate email addresses from other providers than your own. for example if you use T-online or 1&1, then all T-online or 1&1 addresses can not be validated.
