i have been sending a email with a pic as an atatchement to several email addresses. These have been recieved ok except those sent to aol email adresses, after nealy a day i have just recieved a postmaster message "delivery status delayed" i am sending from hotmail.com
May be that Hotmail is hard pressed and is very picky about transmitting to more than one address at a time.
From personal experience (I use Aol) a hotmail user with (local parish council) has the same difficulty sending data but never has trouble receiving it from the rest of the group and neither do they when sending stuff themselves.
this is a common problem with aol (good reason in my view not to use aol, but I don't want to provoke a great debate on this!) AOL, being rather a "nanny state" likes to "protect" its subscribers from anything that aol perceives as a possible "nasty". I regularly send emails to a group of 22 people and all are delivered without problem except for the sole aol one. Actually we've got it fixed now - the recipient with aol had to tell aol to let stuff through (don't know how he did it)and now he receives my emails; with and without attachments.
