Hi there. I recently moved a Multisite to a new server with the same host and since then emails from the site no longer seem to work.
2 sites in particular include plumbershb.co.nz and baytours.co.nz.
The former uses contact form 7 and just won't send and the 2nd one uses Woocommerce bookings and won't send booking confirmation emails despite none of the settings changing.
Any ideas what is blocking these emails?
