I really hate complaining about Dreamhost, I know it may seem like I enjoy it, but I really don't.
This is probably no surprise to some of you. But remember the custom .procmail setups I wrote about a few months back. To catch you up, no one can create a mail user with shell access on Dreamhost anymore. This means that custom .procmail setups cannot be done anymore.(There may be a work around to this, but it has not been accomplished yet) Dreamhost previously told us that anyone who had an email address with shell access would be grandfathered in and would be able to keep it.
Well not anymore. I have received warnings from other Dreamhost users that once your account is "upgraded" in the upcoming migration process, you will lose all custom .procmail setups and all mail accounts will lose their shell access. All of this has happened with NO WARNING for a number of users.
This means you may wake up in the morning and find that your custom filtering no longer works. More and more it looks like Dreamhost no longer wants to host email.
