Up until about last week I was always able to send Email via 3rd party software (Pegasus) using AOL 5.0 I have made no change to either Pegasus or AOL software but now am unable to send mail. I get this message: Delivery has failed on the enclosed message for the following reasons reported either by the mail delivery system on the mail relay host or by the local TCP/IP transport module: 550 relaying to <[log in to unmask]> prohibited by administrator AOL support could not explain but said that they did not support 3rd party software - I guess they have changed something at their end to cause this. I seem to remember the same problem with CompuServe. Can anyone throw any light on this ?
