Admin gets copies (bcc?) of all e-mails I send

My mail admin reports that he gets a copy of all e-mails I send with eM client. How can I stop this?
It doesn’t happen with Outlook or Thunderbird.
The e-mail server is Linux based - a 3rd party virtual server.
The e-mail headings have the following information:
Received: from xxxxxxxxxxxx ([unix socket])
by xxxxxxxxx (Cyrus v2.3.7-Invoca-RPM-2.3.7-12.el5_7.2) with LMTPA;
Wed, 19 Jun 2013 17:25:24 +0000
X-Sieve: CMU Sieve 2.3

I have reverted to using Thunderbird instead.

Please enable SMTP logging for the problematic account, simulate the issue and send us the logs so we can analyze them. Thank you.

Thanks George.
I enabled the logs and sent a single e-mail to the same account.
The content of the log is:

Does this help?

Chris,

Your email username and password are contained in the log you just published, I would advise you to change your password ASAP.

Michael

Thanks Michael. I hadn’t realised as it was encoded. It has now been changed.

Hi,
I am sorry but the log is stripped and it does not contain any relevant information. Could you send me the full log at wilson@emclient.com? Thanks a lot.
