[imp] attachments time out during upload

[Ken Winke]

I'm not sure if this is a feature of Horde, or else a setting I need to 
tweak in apache or php.  I'd like to be able to use attachments through 
horde between 5-10MB.  However, when I try to attach them, it usually 
errors out after 60 seconds.  The occassions I've had it successfully 
attach, it errors out while sending the message...which results in the 
message arriving but without the attachment.

I tried updating the max_execution_time variable in php.ini but that didn't 
seem to make a difference.

Is there a horde setting to allow for uploads that take longer than 60 
seconds, or do I need to tweak a variable in apache?

Also...is this a bad idea?  Should I be capping uploads at smaller sizes to 
prevent overall poor performance through the server or is it successful on 
a fairly current server (dual PIII/866 - 512mb RAM)?

Thanks for any help...
