Large msg attachments cannot be sent - and no error

[orvils]

E-mail with an attachment bigger than 2.1MB is not sending. When I upload the file and push "Send" button the "Sending e-mail" message appears, but after a while it disappears and no other error or message is displayed even when Debug=4.. No errors in logs as well.

On My other server I have this problem with an attachment of 1.1MB already. The difference between servers is that on the one where I have this error at 1.1MB files i have larger PHP vars:
upload_max_filesize = 100M and post_max_size = 110M

What Information could help you?

I only wish to say that I have the same problem, and have considered creating a ticket for it myself. I experience a somewhat higher limit than 2.1 MB, though. In my testing, I have found that when the total e-mail size exceeds cirka 4 MB, the problem occurs. No errors, just like orvils has described.

I'm running Roundcube on Apache2 with PHP5 on a Debian GNU/Linux box. PHP's upload_max_filesize and post_max_size has been set to 64 MB. There was a limit set in the default .htaccess file in Roundcube as well (2 MB) - I have of course removed that.

In other webmails running on the same server (e.g. SquirrelMail?) this is not a problem, so there shouldn't be anything wrong with my PHP configuration.

I hope that you will find time to look into this. Thanks a lot for making a terrific webmail app! Keep up the good work!

Best regards,

I'm becoming very unsure of the real limit here, this time I was able to send an e-mail on about 6 MB without problems, but when reaching about 8 MB the previously mentioned error occurs.

Anyhow, I want to confirm that this is still a problem in 0.1-rc2, and I thought I should mention something about what happens at the SMTP server. Here are some lines from my Postfix log, when the error occured in Roundcube:

Nov 17 18:30:32 dove postfix/smtpd[6824]: connect from panther[10.0.0.15]
Nov 17 18:30:32 dove postfix/smtpd[6824]: E3C90EC7BD: client=panther[10.0.0.15]
Nov 17 18:30:33 dove postfix/smtpd[6824]: lost connection after RCPT from panther[10.0.0.15]
Nov 17 18:30:33 dove postfix/smtpd[6824]: disconnect from panther[10.0.0.15]

"Panther" being the web server hosting Roundcube (Debian Etch with Apache 2 and PHP 5).

Review in 0.1.1 - not sure we can do anythin about it

[maho]

I think that it's related to memory limit.

I have:

max_execution_time = 1000 ; to allow upload big attachment on slow connection
max_input_time = 1000 ; as above

and

memory_limit = 120M ; to allow parse big attachments

But when I attached 2 attachments: one 8mb, another 10mb and clicked "send":

1. I got error in logs/errors:

PHP Fatal error: Allowed memory size of 125829120 bytes exhausted (tried to allocate 25497455 bytes) in /srv/www/poczta-rc.pagema.net/program/lib/Mail/mimePart.php on line 226

I think it's insane that 120MB isn't enough to send 18mb message.

2. compose window is blocked. Buttons don't work and can't do anything but refresh browser.

Can you verify those settings are in effect for the directory RoundCube is in?

<?php phpinfo(); ?>

Also, please check with recent version - 0.1.1 and SVN.
