I restarted Postfix and flushed the queue a few times, but there isn't
any change. It's always trying "notes.uptel.net", never any of the other
2 MXs.
The Postfix client tries a limited number of IP addresses and a limited
number of SMTP sessions.

Number of IP addresses, default: smtp_mx_address_limit = 5.
Number of SMTP sessions, default: smtp_mx_session_limit = 2.

Hi Wietse,
As I said in my first mail, it's already configured with:
smtp_mx_address_limit = 20
smtp_mx_session_limit = 5

I assumed that would be sufficient (they only have 3 MXs). I've increased smtp_mx_session_limit to 50 right now.

perhaps
quick tmp fix use a transport table with static target ip

Thanks for the idea Robert, using a static transport map worked as a quick fix. But I'm still not sure what happened and why.

Best regards,
