PROBLEM
I am getting an error saying an attachment is too big when I try to attach a file of 5MB to an email. How do I adjust the allowable size for email attachments in Atmail?

ENVIRONMENT

• On-Premise Server + WebMail Installations: Version 6.0 > Current Version
• Webmail Only Installations: Version 6.0 > Current Version

CAUSE
Attachment size limit.

RESOLUTION

1. Attachment size is set via the servers php.ini settings file. Normally located at /etc/php.ini.
   

   ; Maximum size of POST data that PHP will accept. 
   ; http://www.php.net/manual/en/ini.core.php#ini.post-max-size
   post_max_size = 8M
   
   ; Maximum allowed size for uploaded files. 
   ; http://www.php.net/manual/en/ini.core.php#ini.upload-max-filesize
   upload_max_filesize = 2M
   

2. Change the size to suit your needs. After making changes, restart Apache.
