When 1AVCenter was created the e-mail sending was done by raw SMTP and it could only access Servers which worked with port 25.
The situation changed drasticaly since then, today people can protect their e-mail contents using TLS or SSL. The e-mail system was redesigned and it now works like a clock.
I am waiting what users will respond. I think it is great but opinions differ sometimes and always add value to the products.
