Usually this works fine, especially with one-way synchronization, but if both sidesĭo exactly the same number of changes, the metadata may end up containing the same values even if This is done by checking the mailboxes' metadata (NEXTUID and Fast synchronization (default) first attempts to find mailboxes that have changed, and.Guarantees that everything will be synchronized, but it's unnecessarily slow for incremental Full synchronization (-f parameter) scans through all the messages in all the mailboxes.There are also three different synchronization algorithms: One-way sync begins to quickly diverge from the source mailbox once changes start to occur onĮither side one-way sync should therefore normally only be used within a short period of timeĪfter a doveadm backup or doveadm sync command was used to synchronize the If both source and destination have UID 6, but the messages are different, the headersĭon't match and both the messages are kept in the destination but they're given new UIDs 7Īnd 8 just to be sure any client didn't get confused about what UID 6 actually was. In this example, UID 1 is kept removed (in destination)īecause UID 1.5 have identical Date+Message-ID headers. Subsequently, UID 6 is delivered to the source mailbox and UID 1 isĮxpunged from the destination mailbox. Example: Source mailbox has messages UID 1.5 source mailbox is sync'd using doveadmīackup to the destination. Only after the first mismatch will changesīegin. Those emails are assumed to be synced correctly. As long as the source and destination side has matching UIDGUID mapping, It fetches the message's GUID (Global UID), which is used to identify any conflicting The one-way algorithm is the same as two-way dsync algorithm except the source account is not Once more to transfer any last new mails from the old mailbox. Multiple times, then switch mails to be delivered to the new mailbox and run doveadm sync -1 Its main purpose is that during mailbox migration you can run doveadm backup This doesn't currently work perfectly, so its use shouldīe limited. doveadm sync -1 performs one-way synchronization, but it merges the changes inĭestination without deleting anything.Both the mailboxes will end up looking identical after the synchronization is It merges all changes without losingĪnything. doveadm sync performs two-way synchronization.If there are any changes in theĭestination they will be deleted, so the destination will look exactly like the source. doveadm backup performs one-way synchronization.You can run dsync in one of three modes: Remote mailboxes can be accessed also via IMAP protocol, which allows using dsync for Server or between different servers (via ssh(1) or tcpĬonnections). It can be usedįor several different use cases: Two-way synchronization of mailboxes, creating backups of mails,Īnd convert mailboxes from/to different mailbox formats. d| destination Description ☜ĭsync (short for doveadm sync) is Dovecot's mailbox synchronization feature. This practice has also caused a number of loops that have made the reflectors to be unavailable to all.Doveadm-sync - Dovecot's two-way mailbox synchronization featureĭoveadm-backup - Dovecot's one-way mailbox synchronization feature Synopsis ☜ĭoveadm sync This practice is NOT DESIRED for the busy reflectors. There have been numerous instances of people intentionally and unintentionally setting up hotspots that cause these reflectors to be linked to other reflectors. We want to encourage people to expand and create new things in Amateur Radio.īUT, we please ask that you do not do any experimentation or linking to the busy reflectors, especially REF001 and REF030. There's a lot of opportunity for experimentation with D-STAR. We are working on the details, but are expecting a number of events on Friday including the DSTAR 101 class.įor more information, check out the DSTARInfoCon page From basic information on what D-STAR is to detailed technical information, This site can hopefully solve any of your cravings! This site is dedicated to helping D-STAR users world wide.
