How do I set my email to read TO: undisclosed recipients?
Outlook Ex----AOL--and others, allow you to leave the TO line blank IF you put everyone else in BCC, and mail is delivered to ----Undisclosed-Recipients:;





HOWEVER. Yahoo insists on an entry on TO line---so common practice is---put your own address on TO and everyone else in BCC. Yeah---you're gonna get the mail same as everyone-----so-o-o, it's easy to delete.
Reply:use bcc and put all address there, recepient address will not appear.
Reply:Put the addresses in BCC then it will show "undisclosed recipients" when the other people receive their e-mail.
Reply:I put my name in recipient address and blind copy {BBC} all other names..it is a good idea to bbc as spammers are looking for a list of addresses @ all times..
