RE: [Exim] Sender address does not resolve?

Hi Juha,

I am very bemused. I have now used ag77-bounces@??? to send an email
to two accounts: chwong74.at.singnet.com.sg and NG_Ee_Ling@???.


I am able to receive the email via chwong74.at.singnet.com.sg but the mail
is queued for NG_Ee_Ling@???. When I look at the data it shows:

The funny thing is if the sender is interpreted as SIZE=1845 and there is no
RCPT TO:, then why is it that chwong.at.singnet.com.sg is able to receive
the email?

By the way, I am using CPANEL/WHM.

CH WONG

Something's going badly wrong here. If you look below, you'll see that
earth.gems2.gov.sg sees the sender in MAIL FROM: as SIZE= 15343.

Furthermore, there is no recipient. What are you using to test?
