Zimbra 220.127.116.11 truncates the message body and attached files!
If the body of the message found Russa letter "I", the Zimbra 18.104.22.168 treats it as the end of the message and the result truncated message body and attachments. This happens only if the letter is used Russian encoding cp1251. In other Russian encodings everything works fine. In version 6.0.5 it worked fine. Prompt please how to fix this error or how to revert from version 22.214.171.124 to version 6.0.5, if possible. The backup is lost.
Thank you. I would be glad of any help.
