I am no "Hmail Server" expert, but according to its documentation, you just need to change the SMTP banner:

  • In the "Hmail server" settings:

    Configuration | SMTP settings | Welcome message

I've seen this before and it's related to the Cisco router. It's performing traffic inspection on the SMTP/ESMTP protocol and blocking anything that doesn't look right.

The 'solution' is to disable ESMTP inspection on the router. The instructions for this are different for each device and I can't find specific instruction for your router. I've included a link that should help, otherwise read the manual: http://www.binarywar.com/2009/11/cisco-pixasa-causes-smtp-banner-corruption/
