I am having troubles sending email with an attachment through rouncube. I did confirm that I can send attachments via IMAP using the Thunderbird email client. I have set PHP memory limit to 32M and the email attachment limit to 12M in roundcube. When I try to send a 2M attachment I get the following 2 lines in the error log:
[21-Jan-2010 07:00:27] PHP Warning: sort() expects parameter 1 to be array, boolean given in /var/www/roundcube/program/include/rcube_imap.php on line 1118 [21-Jan-2010 07:02:11] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 6952037 bytes) in /var/www/roundcube/program/lib/Net/SMTP.php on line 887
It looks like PHP is already exhausting the 32M, but I have no idea why?
First, I freely admit I'm not familiar with the attachment code. But I'd guess some kind of expansion is going on given the numbers you're posting. How many recipients? Recipients * attachment_size * message_body_size * php_overhead = ?? If it's only one recipient, I've not idea other than processing expansion, which seems quite high, given over 32MB being used for a 2MB attachment, that's 16x overhead.
Just a thought.
