[imp] Problems with archives larger than 1MB in compose mode

[Glauco Henrique Riberio de Carvalho]

Hi there!
	Every time I attach an archive or a group of archives that amount of bytes
is larger than 1MB, I observe this message when I click "send" at "compose
page": "Fatal error: Allowed memory size of 8388608 bytes exhausted at
(null):0 (tried to allocate 1661793 bytes) in /usr/share/pear/Net/SMTP.php
on line 207".
	Someone could help me to solve this trouble?

I´m running:
