[SM-USERS] file attachments

[<st...@no...>]

I'm running 3 boxes - all with RedHat 9, standard sendmail, squirrelmail
1.4.4 (upgraded via RPM from 1.4.3A) and no additional plugins.  I can't
seem to send file attachments larger than about 480-500KB.  I've tried all
the obvious remedies - editing PHP.INI (all three of the suggested lines),
looking for any .htaccess files, looking for any LimitRequestBody, or
limitRequestField orLimitRequestFieldsize lines in my httpd.conf, and even
installing WU-FTPD.  Nothing changes, no matter what I set any of the
values in PHP.INI to.  I can attach tiny files but no bigger.  I've tried
sending from Mozilla mail and the problem wasn't there.  Oh yean, this
happens with MSIE and with Netscape.  I haven't tried any other browsers. 
Any hints or suggestions would be MUCH appreciated.

Thanks

Steve Wilson
