Okay, here's the info....running Win ME, IE 6.0, with a Tiny Personal Firewall, and regular 56K dial up.

My problem is that recently I have been receiving complaints from friends that when they send me email it is being returned to them as undeliverable. These are all people who email me regularly, have me as a contact, so the address is correct. It is not a consistent problem, sometimes they can email me, sometimes they can't, and most of them ARE able to reply directly to an email I have sent them and there is no problem. One person who emails me several times a day was unable to send an e-card for my husbands birthday....but regular email gets through just fine....

My question is----is this problem my firewall perhaps, or should I call my ISP and complain about the service? I just wanted to ask here before I call them and look like an idiot complaining about something that is my fault.
