Hi Andrei
Are you talking about the corporate domain swisscom.com or the residential 
domains bluewin.ch and bluemail.ch?
For bluewin.ch/bluemail.ch I can’t locate the deferrals you talking about. 
Could you send us some log examples with timestamp and sending Domain and 
failed recipients to postmas...@bluewin.ch<mailto:postmas...@bluewin.ch> ? 
Perhaps I’ll locate the problem with this additional details. For Swisscom.com 
I’m not responsible, but could forward your detailed Problem to the right 
persons.

Regards
Roland  Meier

Betreff: [mailop] SwissCom contact required

HI guys,

I need a contact at SwissCom. I have found their postmaster page however there 
are only guidelines and not a contact form.
We have started sending to SwissCom and we receive allot of deferrals because 
of the following:
Failed to query ldap/internal error
452 requested action aborted, internal error, please try again later

From their documentation its an internal issue on their part however I still 
want to reach out to them as we have a big client which will be sending to 
Swisscom 😊

Any contact will be greatly appreciated.
