Hello, When I tried to attach a file more than 2MB the webmail get stuck sending the file (files less than 2MB are sent succesfully). The message_size_limit configuration on the main.cf is set to 0 (unlimited). On the php.ini configuration file is set to 25MB. In the past we were able to attached files up to 25MB, the configuration of both files has not been modified. I would really appreciate any idea what could be affected the attachments. Thanks in advance.
