I followed howto and installed ISPConfig 3 on CentOS 5.3. Today I send email to local address with attachment 16MB. Error message "Maildrop: maildir over quota". But I already set mail quota in ISPConfig 3 to 50MB. How can I increase quota for big attachment? Also webmail attachment limit show 2MB.

check the message_size_limit = ??? in the mail.cf file. asper webmail im guessing its somthing similar in squirrel mail or what ever client you are using also maybe check Apache You can restrict maximum file size using [LimitRequestBody] directive. Search for /etc/httpd/conf.d/php.conf and comment out LimitRequestBody. Restart Apache after editing the configuration and you will be able to attach larger files

I don't know where is mail.cf but I see "mailbox_size_limit=0 and message_size_limit=0" in ISPConfig 3. There is no LimitRequestBody in php.conf either. What should I do next?

sorry meant main.cf by mail.cf and next thing I would try is to add a value to message_size_limit= like 100000 or somthing (in bytes)In most cases, let me know what happens.

Yes it work but SquirrelMail still show max attachment size = 2M. Can I increase that?

Ok, I think the squirrlmail config file would have that...I have never set up squirrelmail always been a fan of "Horde". give me a about an hour should be able to figure something out...I got a bench server in the office I will play with

Sorry im a bit late...board meeting grrr. alright well from playing around it looks like squirrelmail uses the php.ini file for uploads and not one of its own. find your php.ini file and follow these steps.

1. Locate your php.ini.
2. open file is some editor.
3. Search for upload_max_filesize.
4. Change 2M to something else, for example 5M.
5. If the upload_max_filesize is larger than post_max_size, you must increase post_max_size so that it’s bigger than upload_max_size
6. If the value of post_max_size is larger than memory_limit, you must increase memory_limit so that it’s larger than post_max_size.
7. Save your changes to the file.
8. Restart your apache web server.


Hope this helps.
