Sorry for my English.
We have problems with the letter "я"(ya), it is necessary return from ver.18.104.22.168 to version 6.0.5. The Backup copy is not present, as have late found out a problem and new copies have rewritten the old. Mail work in the organisation is paralysed. Help please!!! Prompt us how to pull out the certificate, not to generate new (we have 850 users). A question very serious. Zimbra very much it is pleasant, it would not be desirable to refuse it because of problems with the coding.
