Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

I don't really get what you mean.
The only reference to "end of data" I could find in the RFC 821 is:

>end of mail data indication
>      A special sequence of characters that indicates the end of the
>      mail data.  In particular, the five characters carriage return,
>      line feed, period, carriage return, line feed, in that order.

But I can't make the connection to feof.

Could you please elaborate and also give example output of your mailserver (and version, etc.)
Your code snippet gives me this:
string(52) "220 XXXXXXXXX.XXXXX.XXXX ESMTP Postfix (Debian/GNU)
"

It's possibly a duplicate of http://bugs.php.net/bug.php?id=49706 on same platform (W2K3)

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. 

Thank you for your interest in PHP.

See #49706
