Here's a problem that some of us may be coming up against.
I use a Mac Mini as my main (desktop) computer; I run Mozilla Thunderbird on it as my email client. Mozilla's not bad at coping with spam, and I've found the most powerful way to block spam is to use whitelists -- in other words, to tell the system that if the person sending me a message is not in my address book, that message is likely to be spam.
That'll all well and good, but what happens when you travel?
I use an iPad for travel, and use its built-in email client, which is very nice, but incredibly has no spam blocker.
So on a normal day when I should be getting, say, 30 or 40 emails, I get hundreds -- and have to sift through them. On a small device. This sucks.
The solution is -- or rather, one solution is -- to use Gmail. Gmail retrieves messages from my POP3 server using the labourstart.org address; I send messages out from it using my labourstart.org address as the sender and reply-to address.
And Gmail is great at blocking spam.
So now I won't see all the spam messages on my iPad, nor on my smartphone for that matter either (if I ever get around to setting up email on that device ...)
How do you cope with spam when you're travelling? Or in general?
