How to prevent communication interception?
Some readers complain that they did not receive our reply email even in the spam mail box. The most likely reason is because your mail server filters out and discards emails without telling you.
The simple solutions are:
(1) Choose the right email service provider. Consideration includes:
Whether the mail server has the background filtering that is out of your control; how the mail server handles spam mails, throwing away or just placing them into the spam mail boxes? and etc.
(2) Use different communication services.
Because of using different communication channels, a letter that provided an effective and cheap technology solution finally successfully reached one spam box of our emails. This solution solves a big problem for us.
(3) A normal mail box would receive spam mails sometimes. If your mail boxes are too clean, have a check.
