No hyperlink for server name part of multi email text

Question

I am trying to have something like {name1, name2}@server.com where name1 and name2 have hyperlinks of name1@server.com and name2@server.com. This is my code:

\usepackage{hyperref}

\{\href{mailto:name1@server.com}{name1}
\href{mailto:name2@server.com}{name2}\}@server.com

but in the out put, }@server.com has also a link which is }@server.com. The only solution I found for this is to have a space between } and @ which I don't like it. Is there anyway to disable the hyperlink for @ so that the output would be {name1, name2}@server.com where name1 and name2 have hyperlinks of name1@server.com and name2@server.com?

Answer 1

It's the heuristics of the PDF viewer, that turns "}@server.com" into a link. At least with AR9/Linux, the heuristics is defeated, if the dot comes from a different font, e.g. a math font:

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\{\href{mailto:name1@server.com}{name1},
\href{mailto:name2@server.com}{name2}\}@server$.$com
\end{document}

Different method using an invisible explicit space character

The next example inserts an explicit space character after @ to fool the heuristics to see }@ server.com instead of }@server.com:

\documentclass{article}
\usepackage{hyperref}

\newfont{\spacefont}{phvr8r}
\newcommand*{\dummyspace}{%
  \leavevmode
  \rlap{\spacefont\symbol{32}}%
}

\begin{document}
\{\href{mailto:name1@server.com}{name1},
\href{mailto:name2@server.com}{name2}\}@\dummyspace server.com
\end{document}

Remarks:

• An explicit space character is a little tricky, because TeX usually replaces the space with horizontal skip space. Therefore I have used a different font that does have a space character at position 32 (space).
