Hi john, Andreas, Thanks for the replies - had not thought about ndrs so freezing them makes a lot of sense. Just need to figure out how to only freeze those for the domain we are migrating - if possible.

Even easier is just to put 'freeze' in the system filter: # Exim filter freeze and then once everything else is up, remove it and unfreeze everything. You could even unfreeze e-mails a little at a time: $ exiqgrep -zi | head -n 100 | xargs exim -M would unfreeze and deliver 100 e-mails at a time.
