I see that LaTeX does not eliminate the space before Y:
\documentclass{article}
\usepackage{tgpagella}
\usepackage[T1]{fontenc}
\begin{document}
e-mail: Kennedi.Yaccarino@somewhere.com
\end{document}
After searching I found a possible way to fix this is to add the following code just before Y:
.\kern-.15em
But I was surprised that LaTeX does not handle this by default. Am I missing something?
