Email address syntax correction with MLW

This action corrects wrong e-mail address in a source file using unique algorithms. Action result example:

We achieved 100% error correction in real text address lists we had. However, we suppose MLW to restore 95% of theoretically restorable addresses. Addresses are often written in exotic ways, e.g. (my)*(email)!(com) for spam-protection purposes. Intellect of our software cannot match human fantasy so far.

No correct address can be damaged by this action: MLW only attempts to correct incorrect addresses. The list of processed addresses is stored in the log as shown above. Each line starts with the three-letter code (SRC - source address; NEW - corrected address; INV - invalid address, recovery failed), followed by the address line number, colon, and the address proper.

Syntax correction settings

The Wizard will also offer you the following options:

  • Remove ?subject= from addresses. Nominally, providing message subject together with e-mail address is quite allowable, but in most mailing lists this is unnecessary.
  • Add mailbox (user-defined) to domains with no mailbox. Some addresses in a list may be absolutely unrecoverable, e.g.:
    NetSoap <netsoap.com>
    Jane Smith <http://www.jsmith.com>
    mycorp.net
    Sergio <mailto:sergio.com>
    

    MLW cannot detect a mailbox if it is not contained in an address. If this option is disabled, all addresses of the kind will be considered invalid. If the option is enabled and a mailbox is defined (e.g. "info"), the addresses will be restored as follows:

    NetSoap <info@netsoap.com>
    Jane Smith <info@jsmith.com>
    info@mycorp.net
    Sergio <info@sergio.com>
    
  • Remove user-defined substring. MLW will attempt to remove the defined substring from all addresses in the list, both correct and incorrect ones (prior to the restore procedure). The string is case-sensitive (if you set it to "REMOVEIT", the substring "RemoveIt" won't be removed). The substring is searched for throughout the entire address line, including address owner name, if any.
  • Recovery emails by known domains list. If this option is enabled, MLW will recovery emails without first-level domain like mike@hotmail, jane@aol to mike@hotmail.com and jane@aol.com. You can add any number of domains to domains list.
  • Remove known 'REMOVEIT' substrings. This option may affect on valid emails. Addresses like mikeREMOVEIT@hotmail.com and jane@NOSPAMaol.com are syntactically correct and may exist. If this option is on, MLW will try to recovery such emails to mike@hotmail.com and jane@aol.com.
  • Verify emails by first-level domains list. It is the simple check procedure, it compare the first-level domain (e.g., '.com' for jane@somesite.domain.com) with all domains in list. But it helpful to remove 'antispam jokes' in mailing lists, like hahaha@dont.spam, someone@invalid.address and so on. To quality emails verifing we recommend Advanced Maillist Verify.
  • Remove unrestored addresses. If the option is disabled, an address which recovery failed would be written in the destination file unchanged.

The action upon a list of one million addresses takes 5 to 60 second on a machine with Intel Pentium III 933 MHz depending on the number of incorrect addresses in the list and on the recovery difficulty.
