Claim:
A messaging service client device comprising: a user interface device; and a processor communicatively coupled to said user interface device, said processor being configured to: ascertain a proposed recipient for a message entered by a user with said user interface device; determine a set of potential recipients for said message, said set of potential recipients including said proposed recipient; analyze said set of potential recipients to determine whether, among said set of potential recipients, said proposed recipient is a most likely recipient of said message by: calculating a likelihood value for each recipient in said set of potential recipients; and comparing a likelihood value of said proposed recipient with a maximum likelihood value in said set of potential recipients, in which said determination whether said proposed recipient is said most likely recipient of said message comprises determining that said likelihood value of said proposed recipient is said maximum likelihood value in said set of potential recipients; and in which said determination that said proposed recipient is not said most likely recipient comprises determining that said likelihood value of said proposed recipient is less than said maximum likelihood value in said set of potential recipients; and responsive to a determination that said proposed recipient is not said most likely recipient of said message, provide a notification to said user through said user interface device that said proposed recipient is not said most likely recipient.
