Dovecot version:2.2.25

Since we used to keep our email files on widows server, I made the following changes in maildir-storage.h

#define MAILDIR_EXTRA_SEP ','

#define MAILDIR_INFO_SEP_S ":" to "+".

Everything seems working except EXPUNG, The dovecot log is flooded by messages like following:

imap(xxxxx): Error: Mailbox INBOX: Expunged GUID mismatch for UID 7039

Then I read the source code, and found the following lines in maildir-sync-index.c

T_BEGIN {

       guid = maildir_uidlist_lookup_ext(ctx->mbox->uidlist, uid,

                                MAILDIR_UIDLIST_REC_EXT_GUID);

       if (guid == NULL)

             guid = t_strcut(filename, ':');

       mail_generate_guid_128_hash(guid, guid_128);

  } T_END;

I have to change the code to guid = t_strcut(filename, '+');

So, should MAILDIR_EXTRA_SEP be used here instead of ':'?

Thanks,

Steven
