Using server cron, only 1 email sent per wp-cron call

Context:

– Intranet, internal server
– With normal Mailpoet setup, no wp-cron job was ever created (checked with WP Crontrol plugin, and compared with another newsletter plugin which did create a wp-cron job successfully)
– So I decided as last resort to create a cron job on my server. Cron job works, as this output shows: “MailPoet’s cron is ready. Simply setup a CRON job on your server (cpanel or other) to trigger this page.”
– Used the 3 “send by” methods with same result.

Then when the cron job starts, under newsletters, instead of saying “will start soon”, says “9 minutes remaining”, and ONE email from the list is sent.

That’s the thing. Every time the cron is called, only one email is sent.

Any help greatly appreciated!
