I would like to report on my recent findings.
1. I receive 150 to 200 spam emails a day, mainly from the same set of financial services targeting me. About half of them are filtered out to the spam box. This started a few weeks ago, I had been OK for years.
2. I called Swisscom help. I was invited to move all spam to the spam box, and not to empty it, to train the spam filter.
3. As a result, I have today 1'384 spam mails in my spam box. The filter has not improved, and I counted the spams in my inbox; 84 this morming.
4. I set up my bluewin account to forward all my mail to a gmail address. Of course, all the spam was forwarded as well. The gmail account filtered out all the spam, with I am sorry to report, a couple of false positives.
5. I called Swisscom again today. The attendant was very nice and helpful.
- she informed me it was useless to keep my spam box full.
- she offered me an advanced bluewin mail package, free of charge for one year. I accepted, but I am incensed to have to pay for basic email security, and need to find another solution.
6. Going to the Swisscom site, I find the following:
https://www.swisscom.ch/en/residential/internet-subscription/protection-security.html
In short, for a minimal security service, the charge would be 9.90 chf a month.
This clarifies Swisscom's policy.
Hope this helps.
