Email never arrives, no bounce error

[Stelios A.]

Hi all,

I've sent an email to a client many times but never got a reply. When I
contact by phone with the client, he never got the emails nor any errors or
any of emails in his junk folders.

I've searched all my logs and don't got back any bounce message or error
and I can't find a way to troubleshoot this. Email seems to going fine from
my email server (see output below) but never arrives. This is happening in
various email addresses and it has nothing to do with my content on email
as it is plain text.

In the logs below I've replace my email with mydomain and myclient for my
client.
