Question
Please tell me the size limit for emails that can be sent via Email DLP.
Answer
The maximum size for emails that can be sent via Email DLP is approximately 35MB.
However, when sending normal emails, the size may increase by 1.3-1.4 times due to encoding.
Therefore, please send emails considering the size after encoding.
* By setting rules in Email DLP, it is also possible to lower the maximum size of emails that can be sent.
If you wish to do so, please contact HENNGE One Technical Support.
