Hello Sergey!

Thanks for the report and sorry for taking so long to respond. I did not use your patches directly, but they were very valuable in locating the issue.

Please apply patches for dovecot-metadata-plugin v14.

1. dovecot-metadata-plugin-value_nil - fix plugin crach if entry->value == NULL (strlen(NULL) - segfault).

Fixed in 517fa826a9ff If there are more cases where this can create a problem, please tell me. I left the return value of get_value at NULL intentionally, so there is a clear destinction between the backend data format (NULL) and the IMAP frontend format ("NIL") and nil values can be easily detected.

2. dovecot-metadata-plugin-utf7_support - add support metadata for UTF8 mailfolder.

Fixed in 05fc591d2943 I looked at the Dovecot sourcecode and got the impression that mailbox names are always UTF-7 in IMAP, and always UTF-8 in Dovecot. So the conversion has to be always applied.

If you have further bugreports or suggestions, please do not hesitate to tell me.

Best regards, Dennis
