Hi team,

Email with attachment more than 8 MB is not going through and giving 
the error shown below. we are using Horde 5.2.21 which is the latest 
stable release,

Also i have enabled horde debug log and can only see this :
2020-03-18T12:56:31+00:00 ERR: HORDE [imp] Server closed the 
connection unexpectedly. [pid 157556 on line 1160 of "C:\Program Files 
(x86)\Parallels\Plesk\Webmail\horde\horde\imp\lib\Compose.php"]

Also memory_limit we tried to increase it to 512 MB even that doesn't 
help. We are not able to figure out the cause, attachment limit is set 
as 32 MB hence it should work but even 10 MB files are not able to get 
send.
