I have almost 500 members in my site - and I go into the aMember admin area to send out information to my members. It appears that many of the members on my list are not getting my emails sent from within the admin area. However - if I email them directly from my mail app the mails are delivered successfully. Something seems to be happening in the delivery from the admin area. Can you suggest anything to investigate? We are using the php mail function within aMember. Thanks
