Other XMPP users see me disconnected

I’ve been using Google Apps for a while, but for a number of reasons I’m stopping using Google.

One of the steps I want to take is migrate my XMPP-based messaging from Google Talk to Dreamhost. I’ve deleted the Google SRV records, I’ve added the three records described in the wiki.

After a while, I could connect OK with my new user/password at Dreamhost. My contact list was empty (that has sense), so I added all my contacts again (mostly of them from Google Talk).

But… nobody can see me connected. I can talk with them, and see their status, but they always see me disconnected. Even people using Dreamhost XMPP has this problem with me too.

I’ve made the switch 2 days ago, just in case. Some advice? Thanks.
