white horizontal lines appear below slices in email

we're designing our emails in Photoshop then saving the HTML for web.  this generates the table that we then edit the HTML for in Dreamweaver. 

when we send out emails, some email gateways show white lines at the base of the slices, particularly in Comcast.  when viewed through Gmail, iPhone, Entourage or general Mail program on a Mac, the white lines do not appear. 

at first we'd thought this was due to the spacer.gif that is created when the email is not in a grid table.  we created another email based on a grid layout with no spacer.gif and the lines still appear.

we're noticing this on quite a few other companies that send out emails.

anyone have any thoughts on why this might be happening or how to resolve it?  we've come to no conclusions.

thanks in advance.

I wouldn't trust the HTML Photoshop outputs, because generally you'll find thee code generated is over the top and more suitable for web browsers than an email. That aside, it would help to see your HTML to see where you've gone wrong.

Tony, it helps if you post your code then people can help you out.

One thing to check is whitespace in your HTML code - sometimes spaces between the end of one TD and start of the next, or between images, can manifest as odd white gaps in the rendered HTML.

Removing those spaces (and breaking your HTML lines inside tags instead) can help in that case.
