What is email error 552 ‘5.3.4 Message size exceeds fixed maximum message size’Įvery mail server has custom settings for the size of mails users can send and receive through it. If the bounce happens due to the content of the attachment, the error message would be similar to error 552 – ‘5.7.0 Our system detected an illegal attachment on your message.’

The error message seen by the senders in the bounce mail in cases of huge attachment size limit would be error 552 – ‘5.3.4 Message size exceeds fixed maximum message size’. In these servers, we’ve seen huge attachments or unsupported attachments formats causing email error 552. Our Support Engineers support hundreds of Exchange servers for web hosts, web designers and other online businesses.

I really appreciate if anyone can help me with this.Users sending messages with attachments to recipients hosted in Exchange servers can end up receiving bounce mails due these attachments. is there a way to fix bluestacks blackscreen and keep OptimzedFramePacing=true? I know OptimzedFramePacing=false should result in a little jitter. changing OptimzedFramePacing only if we run in bluestack, which is impossible because OptimzedFramePacing can not be set at runtime. (blitType, Custom main manifest, Changing Graphic API) fixing bluestack black screen by any other ways. In the last few days i have searched and read all the topics about this, which are very few considering it looks like a big issue! I have tried with empty project with only a few rigidbody2d falling and result is the same. The only solution I have found for it is to disable 'OptimzedFramePacing' in PayerSettings when building which fixes the blackscreen, but causes another problem, which is: on android your game gets a little jittery. The Problem: when running a unity build in Bluestacks you get a black screen.
