One minor gripe:

> +         if (strchr(port->user, '@') == port->user + strlen(port->user)-1)

This code is correct, but it tempts someone to replace the strchr()
with a single-character check on the last character of the string.
Which would introduce the security hole we discussed before.  The
code is okay, but *please* improve the comment to point out that you
are also excluding the case where there are @'s to the left of the
last character.
