I used LMTP command like RCTP to: "uid+folder@domain".
The deliver is succeeded when I use the folder name without any whitespace inside.
RCTP to:<[email protected]">
But I get "500 5.5.2 Syntax error in recipient address" when I use the folder(test test) contains whitespace.
RCTP to:<test+test [email protected]">
Please help.
