[Dbmail] Error in dbmail-imapd

[Hans Kula]

After testing i found one more character to add: "," and "&"

It seems as if oe is escaping special chars with &xxx- and &x,x- ...

so array in imap4.c must look like this: 

const char AcceptedMailboxnameChars[] =
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-=/ _&,";
