You can put dot anywhere in your ID
i.e, email@example.com as firstname.lastname@example.org, email@example.com
if u give these Id to anyone mail will come to your inbox only
If your frnd ask your ID impress him/her by giving ID like YourID+frnds firstname.lastname@example.org
ex: To my frnd Vinay i could give ID as email@example.com……again mails comes 2 u’r inbox only
also like firstname.lastname@example.org
No need to change settings anywhere,just try sending mail from other ID to gmail…..u will be amazed…
One more option is [email protected] .
