[TYPO3-windows] Mail problem

[Maurice]

Hi,

After installing Typo3 and setting setting 
$TYPO3_CONF_VARS['SYS']['systemLog'] = 'Mail' , i get the folowing error 
messages on
every page of my site:

----------------------------------

----------------------------------

Strange thing is that the mail is still sent. I don't know whether there is 
a relation, but in tt_products i get the folowing error when sending mail:

----------------------------------
Warning: fsockopen(): unable to connect to :80 in 
E:\www\mydomain.com\htdocs\t3lib\class.t3lib_htmlmail.php on line 1277

Fatal error: Maximum execution time of 60 seconds exceeded in 
E:\www\mydomain.com\htdocs\t3lib\class.t3lib_htmlmail.php on line 1277
----------------------------------

Can anyone help me?

Maurice
