Rule-based electronic message processing

A non-transitory computer-readable medium for processing a first e-mail, said e-mail having a sender and a plurality of recipients, said medium comprising computer-executable instructions thereon for:

• prior to transmitting said e-mail to the at least one recipient:
• reviewing 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 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 incorrect comprises:
• calculating a first number of e-mail addresses from the plurality of e-mail addresses having the same domain name as the sender;
• calculating a second number of e-mail addresses from the plurality of e-mail addresses having a different domain name than the sender;
• determining a ratio of internal to external recipients based on the first number and the second number;
• and
• determining that said e-mail address information for at least one of the plurality of recipients is potentially incorrect based on a ratio of internal to external recipients of the e-mail message;
• upon determining 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 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.

A computer-implemented system for processing a first e-mail, said e-mail having a sender and plurality of recipients, said system comprising:

• a computer system comprising a processor and operatively associated non-transitory memory, wherein the memory comprises instructions that, when executed by the processor, cause the computer system to:
• prior to transmitting said e-mail to the at least one recipient:
• review e-mail address information for the plurality of recipients of said e-mail, wherein said e-mail address information comprises at least one e-mail address;
• determine 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 a first number of e-mail addresses from the plurality of e-mail addresses having the same domain name as the sender;
• calculating a second number of e-mail addresses from the plurality of e-mail addresses having a different domain name than the sender;
• determining a ratio of internal to external recipients based on the first number and the second number;
• and
• determining that said e-mail address information for at least one of the plurality of recipients is potentially incorrect based on a ratio of internal to external recipients of the e-mail message;
• upon determining 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
• permit 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.
