I sent a email with addressee "firstname.lastname@example.org"
first email was sent ok. got an reply back from friend.
reply to his email..
failed delivery messages back...
look into the message....address was changed from from email@example.com to firstname.lastname@example.org
thus it was undeliverable.
ok..used the email.. edited the address to correct one again email@example.com
fail delivery again.
I ended up using web yahoo mail to send. don't understanderd why 1st email sent ok..then failed twice.
anyone had similar problem?
