The difference of PowerMTA and Open source applications <br /> <br />Why PowerMTA is better than Open Source Applications? <br /> <br />Some people argue that there are various of open source applications <br />available in the market today, like exim and Gmail that allow users to <br />send mass e-mails too. Then why should a person invest in a costly <br />tool like PowerMTA? If you are also of the same opinion then do have to take <br />a look at the reasons that justify the claim that PowerMTA is yet still by far <br />better than Open Source Applications: <br /> <br />•PowerMTA allows you to create a collection of IPS from which you can send mails on a regular basis <br />•PowerMTA allows the users to send a large number of e-mails at a single point of time <br />•PowerMTA is very fully equipped to abide by the throttling limits set by different ISP’s <br />•PMTA has an effective bounce processing mechanism <br />•PowerMTA also supports implementation of key e-mail authentication methods like DKIM and DK.
