There are quite a lot of changes since v2.2.25. Please try out this RC so we can get a good and stable v2.2.26 out.
- master: Removed hardcoded 511 backlog limit for listen(). The kernel should limit this as needed.
- doveadm import: Source user is now initialized the same as target user. Added -U parameter to override the source user.
- Mailbox names are no longer limited to 16 hierarchy levels. We'll check another way to make sure mailbox names can't grow larger than 4096 bytes.
- Added a concept of "alternative usernames" by returning user_* extra field(s) in passdb. doveadm proxy list shows these alt usernames in "doveadm proxy list" output. "doveadm director&proxy kick" adds -f <passdb field> parameter. The alt usernames don't have to be unique, so this allows creation of user groups and kicking them in one command.
- auth: passdb/userdb dict allows now %variables in key settings.
- auth: If passdb returns noauthenticate=yes extra field, assume that it only set extra fields and authentication wasn't actually performed.
- auth: passdb static now supports password={scheme} prefix.
- imapc: Added imapc_max_line_length to limit maximum memory usage.
- imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs. This replaces at least partially the rawlog plugin.
- dsync: Added dsync_features=empty-header-workaround setting. This makes incremental dsyncs work better for servers that randomly return empty headers for mails. When an empty header is seen for an existing mail, dsync assumes that it matches the local mail.
- doveadm sync/backup: Added -I <max size> parameter to skip too large mails.
- doveadm sync/backup: Fixed -t parameter and added -e for "end date".
- doveadm mailbox metadata: Added -s parameter to allow accessing server metadata by using empty mailbox name.
- master process's listener socket was leaked to all child processes. This might have allowed untrusted processes to capture and prevent "doveadm service stop" comands from working.
- auth: userdb fields weren't passed to auth-workers, so %{userdb:*} from previous userdbs didn't work there.
- auth: Each userdb lookup from cache reset its TTL.
- auth: Fixed auth_bind=yes + sasl_bind=yes to work together
- auth: Blocking userdb lookups reset extra fields set by previous userdbs.
- auth: Cache keys didn't include %{passdb:*} and %{userdb:*}
- auth-policy: Fixed crash due to using already-freed memory if policy lookup takes longer than auth request exists.
- lib-auth: Unescape passdb/userdb extra fields. Mainly affected returning extra fields with LFs or TABs.
- lmtp_user_concurrency_limit>0 setting was logging unnecessary anvil errors.
- lmtp_user_concurrency_limit is now checked before quota check with lmtp_rcpt_check_quota=yes to avoid unnecessary quota work.
- lmtp: %{userdb:*} variables didn't work in mail_log_prefix
- autoexpunge settings for mailboxes with wildcards didn't work when namespace prefix was non-empty.
- Fixed writing >2GB to iostream-temp files (used by fs-compress, fs-metawrap, doveadm-http)
- director: Ignore duplicates in director_servers setting.
- zlib, IMAP BINARY: Fixed internal caching when accessing multiple newly created mails. They all had UID=0 and the next mail could have wrongly used the previously cached mail.
- doveadm stats reset wasn't reseting all the stats.
- auth_stats=yes: Don't update num_logins, since it doubles them when using with mail stats.
- quota count: Fixed deadlocks when updating vsize header.
- dict-quota: Fixed crashes happening due to memory corruption.
- dict proxy: Fixed various timeout-related bugs.
- doveadm proxying: Fixed -A and -u wildcard handling.
- doveadm proxying: Fixed hangs and bugs related to printing.
- imap: Fixed wrongly triggering assert-crash in client_check_command_hangs.
- imap proxy: Don't send ID command pipelined with nopipelining=yes
- imap-hibernate: Don't execute quota_over_script or last_login after un-hibernation.
- imap-hibernate: Don't un-hibernate if client sends DONE+IDLE in one IP packet.
- imap-hibernate: Fixed various failures when un-hibernating.
- fts: fts_autoindex=yes was broken in 2.2.25 unless fts_autoindex_exclude settings existed.
- fts-solr: Fixed searching multiple mailboxes (patch by x16a0)
- doveadm fetch body.snippet wasn't working in 2.2.25. Also fixed a crash with certain emails.
- pop3-migration + dbox: Various fixes related to POP3 UIDL optimization in 2.2.25.
- pop3-migration: Fixed "truncated email header" workaround.
Since v2.2.25 up to v2.2.26.rc1 on Ubuntu 16.04.1 LTS Dovecot is compiling successfully but "make check" is throwing out the following:

Note: see also the FAQ in the source distribution. It contains workarounds to several common problems. In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind version, and what OS and version you are using. Thanks.

This is an issue with either valgrind or openssl. See https://bugs.launchpad.net/ubuntu/+source/valgrind/+bug/1574437
