joomla - $mailer->addAttachment() not sending (or timing out) large files -

currently able send attachments using joomla

$mailer = jfactory::getmailer(); $config = jfactory::getconfig(); ... $mailer->addattachment($filepath);

i able send attachments of little sizes (i've tested 1-100kb of different file types including .pdf) when tried attach 1.7mb pdf file. page stops loading after seconds white screen. tried check in developer mode , says ("failed load response data.").

do guys know how go this? max upload issue or request timed-out maybe because of slow upload?

thanks in advance.
