I'm trying to put a horizontal rule in an email, but actually using 100% width 1px high table/td.

I've trawled the forums/stackoverflow etc and can't yet find a solution that works across all Outlooks AND Lotus 6,7,8 (as well as the other clients but they're less problematic)

I guess it would be possible to do an if(!mso) and if(mso) rule and double up the content as I have some options that work in Outlook and some that work in Lotus but not both .. that's not ideal though

anyone have anything reliably working yet?

I am happy to test any suggestions in Litmus and post the results.
