So what method do you suggest us to obfuscate? All the common ones are known by email harvesters...

We can use gd and embed the e-mail addresses in images... although it's easy, it's quite cpu intensive...

And it would complicate the mirroring process...

I don't see how this is a PHP website issue.  this happens anywhere/everywhere you may post an email address.  If you wish to obfuscate your email, that is upto you.  

AFAIK, we're talking only about the bugsystem, not about the annotation system or something else... 
The bugsystems relies on valid email addresses... IMO this is indeed a php.net website problem. Reopening.
(BTW: the bugsystem doesn't get mirrored so that's not a problem)

What about using a table to display the address?

<table><tr><td>user</td><td>randomobfuscate</td><td>domain.tld</td></tr></table>

Btw, I like the image idea. But it doesn't have to be that cpu intensive, we could cache the images (create a md5 sum of the email address which acts as a filename or so).

We could use that function from the PHP manual which converts the email addresses displayed on the web in a similar format to:

  jacques at php dot net

I can grab the code from the phpweb and implement it here.

AFAIK there is no such function. What you write in as your email address is directly used for user note printouts...

On the online user manual I see (http://www.php.net/manual/en/) at the bottom of that particular page there is:

  mj at php dot net

We can easily do using something like above using the following code snipbit:

  $name = str_replace(array("@", "."), array(" at ", " dot "), $name);

Maybe I'm going insane.  I've found it from my guestbook code *G*

I don't see any problems in using obfuscated adresses, but don't make too much of an issue out of it...

Why not just use something like the <table>-idea?

The crawlers are scanning the HTML for adresses, and most of them won't find anything if it looks like this: someone<!-- bla -->@<!-- bla again -->example.com

The "obfuscation" used currently is IMHO OK as is. I don't think so, that too much people would like to ask questions from those submitters.
