There's lots of us out there who haven't caught on to the world of internet, email and chat room slang and abbreviations.  Just thought you might find this article interesting.  Abbreviations change so fast it's hard to keep up.  But this list might give you a chuckle or two.  WARNING: some of the abbreviations might be offensive.  Please don't hurt the messenger (me!)\n\nhttp://netforbeginners.about.com/cs/netiquette101/a/abbreviations.htm\n\nplrr

It depends, if you get HOST UNKNOWN it means that the part of the address after the @ is wrong, if you get USER or MAILBOX UNKNOWN, then it's the part before the @ and if you get MAILBOX QUOTA EXCEEDED or MAILBOX FULL, it's because the person's mailbox is full .  \n\nCall and Have them send you mail, then reply.

1. See if it has a valid name before the "@" symbol.\n2. Only one @ symbol should be there\n3. After the @ symbol there should be a domain with atleast one "." dot with valid ending region like com, in, ca etc.\n\ndont get the feeling..arrrrrrrrr.. :)\nyou can not verify an email address without actually sending it..if its valid it will reach its destination.. otherwise it will bounce back to you.

These are the telltale marks of being forwarded. when the email is forwarded, the server adds the marks,and so on, until the paragraph is spilt up into many lines, with these marks at the beginning. it's a good way to tell if people sent a forwarded message - even if they delete the Fwd in the subject line....
