According to the findings it can be noted that aboutsixty percent of the organizations have not any plan for the security awareness training for theemployees using e-mail for the operational activities. This report focuses on a research on the e-mail security in which problems related to the e-mail security has be proposed including theaddresses that could be helpful in mitigating such problems. Pretty Good Privacy has been alsoaddressed in this report that could be helpful in intruding the traffic system of informationexchange.E-MailE-mail (Electronic mail) can be defined as the exchange of messages stored in the systemusing telecommunication those are generally encoded using ASCII coded text. This also enablesthe users to share non-text files that include images, gifs, audio files, and others in the form ofattachments that could be sent in binary streams (Petry et al., 2014).

It is all about training the employees about the e–mail policyand creating awareness among them about practicing these policies in the real situations(Ossullivann et al., 2017). Considering the facts related to the outbound email, it can be statedthat training and policy should cover much broad topics related to what are the objectives thatneeds to be considered as a confidential information and which should not (Gu & Fang, 2012).Other objectives are: the appropriate information that should be included while sending outgoinge-mails and restriction for the personal use of the email. Regarding the policies for the usage ofe-mail services, it can be recommended that companies should develop an independent policy forthe encryption of the files and texts while exchanging between two users. There should be accessof these encrypted messages to the limited users and should not be allowed for every employeesto access these information. Pelland (2015) stated that “this can create a security risk. Autoforwarding means the email is sent to an account that isn’t under the control of the ITdepartment”.Basic Principles of E-Mail SystemThere are three basic principles of e-mail system that can be listed as:Basic Communication ProtocolThe transmission of e-mails is takes place through the means of POP3 and SMTP basicprotocols including its expansion agreements.
