I get that kind of crap when using Yahoo Mail all of the time, and more. Plenty of scams where someone (usually in Nigeria) is telling me that they want to "share" their fortune with me, but needs a bank account to "deposit" it into. Yeah, right! Yahoo does the sorriest job of all of my email providers. Perhaps that's why the corporation is on shaky ground.
With Windows Live Hotmail, I get a piece of spam once in a while, but it usually goes into the "junk" folder, if not, I put it there. They do an excellent job of filtering out the crap from the good.
GMail does a good job too, I get an extra piece of spam or two a week, but once I mark them as such, it goes into the spam folder. Actually, I wanted GMail for their free web phone. From the GMail account, one can make calls to the US & Canada for free, no limits. All that's needed is the voice & chat plugin, which takes a minute to install. Although I can talk through the PC, I prefer the headset.
Thunderbird, I tried, but it was too complicated to setup.
AOL, some junk, the spam filters helps, but nowhere near as reliable as Windows Live.
OperaMail, administered by FastMail, the free version has virtually no spam control. One can mark a piece of spam as such, but it shows right back into the regular mail box.
EarthLink Web Mail, my ISP based email service, does a good job. Although I use it little, it filters out known spam & the customer never sees it. There's a chart that shows how much (as a percentage) of emails that's spam.
OperaMail, I mainly use it for forum use, no business.
Yahoo Mail, I use it for businesses who I expect as known spammers, or those who sells their lists.
AOL, some business, some forums.
Windows Live Hotmail, my main account for business only. I don't use this account for any other purpose.
EarthLink, I've not used much, mainly to obtain trial software.
GMail, an all around good account. The free phone service is worth a fortune to have. I use it an hour or so per day.
