"No transport provider was available"

[Davi]

Work colleague tried to send out a group email last night (about 25-30 recipients in total) but this morning has received a report back listing every recipient with the message after it stating:

"No transport provider was available for delivery to this recipient."

Given that every person on the list is at a different domain, I find it somewhat unlikely that they all had internet problems, but then neither did we... emails I sent out last thing all got through fine!

Where do I start looking for the problem?

many thanks - just gone through the list and one email address contained a space instead of an underscore. Didn't realise one in a list could bugger them all up, thought it only affected that one email.
