Patent ID: 8621007

Claim:
A computer-implemented method for processing a first e-mail, said e-mail having a sender and a plurality of recipients, said method comprising: prior to transmitting said e-mail to the plurality of recipients: reviewing, by a computer system, e-mail address information for the plurality of recipients of said e-mail, wherein said e-mail address information comprises a plurality of e-mail addresses; determining, by said computer system, that said e-mail address information for the plurality of recipients of said e-mail is potentially incorrect, wherein the determining that said e-mail address information for the plurality of recipients of said e-mail is potentially incorrect comprises: calculating, by said computer system, a first number of e-mail addresses from the plurality of e-mail addresses having the same domain name as the sender; calculating, by said computer system, a second number of e-mail addresses from the plurality of e-mail addresses having a different domain name than the sender; determining, by said computer system, a ratio of internal to external recipients based on the first number and the second number; and determining, by said computer system, that said e-mail address information for at least one of the plurality of recipients is potentially incorrect based on the ratio of internal to external recipients of the e-mail message; upon determining, by said computer system, that said e-mail address information for the at least one recipient is potentially incorrect, prompting said sender to evaluate whether said e-mail address information is correct; and permitting, by said computer system, said e-mail to be transmitted to the at least one recipient upon receiving an indication from said sender that said e-mail address information for the at least one recipient is correct.
