IF I SEND AN EMAIL TO MYSELF, JUST ONE WORD AS A TEST, I HIT "SEND", AND IT IMMEDIATELY GOES AND ARRIVES, AS PER NORMAL. FINE. IF I SEND EXACTLY THE SAME ONE WORD EMAIL TEST TO, FOR EXAMPLE, MY WIFE, OR ANY OTHER INDIVIDUAL RECIEPIENT, IT TAKES A LONG TIME TO EVEN SEND. I GET A PROGRESS BAR AS IF I WAS SENDING A LARGE RAW FILE OR SOMESUCH. LIKEWISE IF I SEND THE EMAIL TO ME AND CC IT TO ONE OTHER PERSON IT TAKES AGES TO SEND. ONLY AN EMAIL TO MYSSELF ALONE WORKS AT THE USUAL SPEED. MY BROADBAND SPEED IS FINE. I HAVE USED THUNDERBIRD FOR YEARS ON DIFFERENT LAPTOPS AND DIFFERENT COMPUTERS WITHOUT THIS ISSUE. I DO NOT KNOW WHAT TO DO, CAN YOU HELP?
