I'm expecting quite weird newsletter behaviour: When I try to send it, it works for a while and then gives flash-info "Sent newsletter to mailing list. Sent 9 emails successfully." But when I "Sent Status Report" tab, it shows sth like this in the attachment.
... and the emails actually doesn't come to subscribers. (I checked, email eddresses in Submissions are stored properly)
When I choose "send test to..." option howether, it arrives to the one given email.
And when I choose "Send to only people not previously sent to" it tells me: "Resent newsletter to mailing list. Sent 0 emails successfully." as if they were succesfuly sent earlier (which they didn't...)
Does anybody have any clue what could be wrong / how to fix this?
