Package: ssmtp
Version: 2.61
Severity: important
I built SSMTP on Solaris 10 using the gcc 3.4.3 as supplied by Sun
Microsystems. I found that when I sent mails using PHP's mail() function
through a web interface that the date was mangled. There was no day of the
month, but instead there was a %_d string in its place - Date: Wed, %_d Mar
2006 15:20:07 +010. A sample mail is below.
The problem was reproducible when compiling with the Studio 10 C compiler from
Sun.
I found the cause of the problem to be in the file arpadate.c on line 82:
const char *format = %a, %_d %b %Y %H:%M:%S %z;
In this line, the day number of the month is as a %_d, which seems to be
incorrect. I changed the line and removed the _ so that I had the following:
const char *format = %a, %d %b %Y %H:%M:%S %z;
After this change and a rebuild, ssmtp sent the mails with a correct and
unmangled date - Date: Wed, 15 Mar 2006 16:01:03 +0100
I have been unable to verify if this bug exists on a Linux system as testing
in the environment I have to work in is not possible.
Additional information which may be useful is as follows:
# uname -a
SunOS devel 5.10 Generic sun4u sparc SUNW,Sun-Fire-V440
# gcc -v

The PHP script that was called in a browser is (the actual receiver address

?php
$to = '[EMAIL PROTECTED]';
$subject = 'Testmail';
$message = 'Body';
$date= date(d M y, G:i:s);
if ( mail($to, $subject, $message) == TRUE)
{
echo OK: $date, mail($to, $subject, $message);
}
else
echo Failed;
