I configured postfix and dovecot on Debian 6.0. I have set high limits both for my php and my postfix configuration file, but I am still unable to receive large email messages or messages with large attachment files (5 MB or greater) via the SquirrelMail client. I checked the log and all seems to be going well; is there any configuration I should look for or something I missed?
Thanks.

What paraemters did you change?
On a CentOS 6 box, the /etc/php.ini has upload_max_filesize as 2MB. Was this the parameter you changed? I believe postfix’s default max size is 10MB, so there should have been no need to change that.
If it’s a PHP error, the problem won’t be in your maillog. It will show up in the web server logs.
In your maillog, do you see the SMTP transaction?
