The best thing about this is that it has an inbuilt spam filter which blocks any suspicious emails from reaching your inbox, so you don't have to worry if something goes wrong with sending or receiving email using SMTPServer! It's not very user-friendly though - I find myself having trouble figuring out how everything works sometimes when setting up new accounts for clients etc., but once set things are easy enough unless there really IS some problem (which doesn’t happen often). If someone can make their software more intuitive then they will be doing themselves well by adding features like auto replys/headers as people seem confused at what each button does most of time even after reading documentation over several times!! As mentioned above; we use ohmysmtp mainly because its builtin SPAM filtering makes our life easier than managing multiple antiSPam services such us Mailtrap + Spaminator Pro combination would require too much work since both apps do similar tasks separately anyway :).
