I've recently moved my emailacount from my own mailserver to dreamhost and have come across a few things that I can't solve (so it seems):
Removed custom mx records, and hit the 'make me a regular' so it'll add DH's mailservers. The servers show up but DNS takes forever to update. This could be solved by patience so I'm not nagging about that just yet
What does bother me is that another custom MX i've moved back to DH is working for some accounts, but seems to be a problem for others (on the same domain). Some of them have that little clock behind them, which is normal, but the clock just stays there! (even after an hour). I can send mail (since "i'm using a local smtp server), but when I send a mail to the 'new' account it bounces with the message 'user m123456' unknown. Should it take this long to add a user??
--- edit ---
as usual, within 10 minutes of me posting this, the clock vanishes wish I was more patient now and then, but an hour for a mailaccount seems a tad long. But anyway, this part is fixed.
