As many of you undoubtedly know, once you set up an email address at a Dreamhost domain, you can go into Mailbox Manager for that address, where you can find instructions for checking webmail and for setting up your email client.
There is only one problem: the instructions are wrong. I have used them for years and had no reason to suspect there was a problem with those settings. Furthermore, I have opened more support tickets in the past few months than the past few years previous, every single one of them about email problems, and not once did a support person ask me about these settings or advise me they are less than optimal.
In Mailbox Manager, you are told
"To check your email go to webmail.yourdom.ain, then enter the first part of your email address, before the @, and your password to sign in."
--- this is no longer correct; you need to enter the full address. (This may be obvious to you or me; it's not to everybody.)
Mail client settings are given as:
Incoming mail server: mail.yourdom.ain (your domain is literally listed there)
Outgoing (SMTP) mail server: mail.yourdom.ain
--- this is no longer correct either.
I just stumbled over a KB article here on Email client configuration. It says, in part,
"There is only one recommended servername (hostname) you should use at DreamHost. It's your specific mail cluster name your account is assigned to. In the past, it was possible to use mail.example.com to connect (where example.com is your actual domain name). Due to how modern mail clients handle security, this is now NOT recommended as it may throw connection errors. Please ensure you are only using your mail cluster servername when connecting."
Gee, ya think you could maybe update the mailbox manager instructions, to reflect these changes? or tell people about them when they are dealing with email problems? or find some creative way to let people know where to find the correct settings? I had literally no reason to look beyond the mailbox manager for settings. I have no idea if any of the email problems I've been having are related to these settings. But I assume that there is a reason for the new recommendation, and that I would be less likely to have problems if I used those recommended settings.
Since I clearly have to have every customer on every domain make changes to their email settings, I'm going one further and moving all that mail to dedicated email provider MXRoute. I've moved one domain over from here to there and couldn't be happier.
If you're keeping your email here, make sure you ignore the customized settings you are given with every single Dreamhost mailbox, and advise all your customers to do so as well.
Maybe I'm the only person who wasn't aware of this. But if not, you're welcome.
