sending email from OTRS above 10K not working

[zealny]

Hello,

I have strange problem.

If I try to send email using 'Communication' > 'E-mail Outbound' or '- Reply -' with attachment of more than 10K or body text of 10K or more of size then article is stored but screen shows error as "An error occurred while parsing CGI reply" and email is not sent.

Attachement in incoming mail above 10k is accepted and ticket is created. I am having problem with only outgoing emails.

nginx file has

Code: Select all

  fastcgi_buffers 8 16k;
  fastcgi_buffer_size 48k;

I am using OTRS 5.0.13 on ubuntu 16.04, nginx/1.10.1 on VirtualBox

Please help

Thank you,
