I’m one of those folks. It was mostly over spam filtering rejecting posts that it shouldn’t, especially messages from the lists that seemed to be coming from my email address. And rejected messages lead to unsubscribing. I got fed up with re-enabling my subscription every week or so.

I considered this, so I first tried another provider (neither Yahoo! nor GMail). It turned out to be blocked from posting to mailing lists. I waited a week for this to sort itself out, but that didn’t happen. So I thought I’d complain/open a ticket/something. I searched their site and couldn’t find a support email address. The troubleshooting flowchart ended with a phone number. I spent 20 minutes on hold and then 10 more with the firstest or first-line support (“yes, I’m sure I have an account.  Yes, I’m logged in. Yes, I’m sure the other SMTP server is up”). He gave me the number for the second line of support. In the US. So I gave up, especially since their IMAP didn’t work with my client.

It looks like there’s a lot of providers out there, but there’s not that many who work correctly.  So I ended up with a GMail account like many others.
