You can probably fix it by changing the port that the iPad is using to send email, probably to port 465 or 857, which are typical ports supported when the ISP blocks port 25.


I should have explicitly said that it's only when she sends to her husband's email that it's a problem. Everyone else gets mail.

I haven't tested against other verizon.net accounts, though...
