Zarafa-webaccess attachment disappeared when I reply to an email but no to a New email. Zarafa version installed is WebApp 1.6-46049, ZCP 7.1.14-51822.
Attachment will not show up at the receiver's Inbox and in my Sent Items.
I tried using Firefox and Chrome and had the same result.
Solution: Increase the MaxExecutionTime, MemoryLimit, PostMaxSize on PHP server where you have the Zarafa server installed.
On SME Server Contribs, you do it by issuing the following commands:
db configuration setprop php MaxExecutionTime 4800
db configuration setprop php MemoryLimit 250M
db configuration setprop php PostMaxSize 40M
expand-template /etc/php.ini
/etc/init.d/httpd-e-smith restart
Update Nov 2016:
We are still having issues with the attachment but it's intermittent, this time I updated the WebApp to the latest version compatible to the server's OS.
