OK I have a BT email acocunt
I have 4 sub accounts
I can email 2 of them & they can email me - no problem (DH & DD's)
I can email my main address form the other 2 but I can't reply & if I send an email from my main account it never arrives
DH & DD can both email the 2 accounts in question & receive emails form it
Why?? It's very odd
How do I fix it?
What am I doing wrong?
