crypt() passwords are never more than 8 characters - anything beyond
8 characters is discarded.
Do not use the Crypt-PW authentication-scheme. Instead use the MAIL_FROM
or PGP scheme instead.
MAIL_FROM is even less secure than CRYPT-PW. Use PGP :)
If you must use CRYPT-PW then the following suggestions are recommended:
- Password should be at least 10 characters in length.
Again, anything over 8 is useless.
All in all NetSol still hasn't learned.
