Dsync migration with shared folders
by George Dimakopoulos 06 Feb '17

Hi everyone, We discovered that the migration path from a VPS to our 2XHP replication server environment with shared folders should be: 1) Rsync all domains from the VPS to serverA. Then rsync all domains from ServerA to ServerB. ServerA & ServerB are in a identical state. 2) Create an empty directory for the shared indexes 3) Start dovecot on both machines. If we did not sync both machines then dsync could not replicate the domains that contained shared folders. What is the right migration process for domains with shared folders ?

dovecot/auth CPU spikes
by nicolas＠andrillon.net 05 Feb '17

Hi All, I have recently moved by webmail server from a VPS to a hosted dedicated server running Ubuntu 16.04. Everything is fine except that login is particularly and consistently long (around 4-5 seconds). I have noticed that the process dovecot/auth seems to eat all of the resources of one of the cores available on the host during login. The authentication backend is a postgres database which is running absolutely fine. I have been scavenging on the dovecot mailing list for some time but I have not been able to find a solution to my problem so decided to send this bottle to the sea. Here is my config: $ sudo dovecot -n # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 3.14.32-xxxx-grs-ipv6-64 x86_64 Ubuntu 16.04.1 LTS ext4 auth_cache_size = 10 M auth_mechanisms = plain login default_internal_user = vmail first_valid_uid = 0 mail_location = maildir:/home/data/vmail/%d/%n mail_plugins = " fts fts_solr" mail_privileged_group = vmail maildir_stat_dirs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Archive { auto = subscribe special_use = Archive } mailbox Drafts { auto = subscribe special_use = Drafts } mailbox Junk { auto = subscribe special_use = Junk } mailbox Sent { auto = subscribe special_use = Sent } mailbox "Sent Messages" { special_use = Sent } mailbox Trash { auto = subscribe special_use = Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { antispam_backend = pipe antispam_mail_notspam = learn_ham antispam_mail_sendmail = /usr/bin/rspamc antispam_mail_sendmail_args = -h;localhost:11334;-P;q1 antispam_mail_spam = learn_spam antispam_spam = Junk antispam_trash = Trash fts = solr fts_solr = break-imap-search url=http://localhost:8080/solr/ sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /var/lib/dovecot/sieve.d/ } postmaster_address = postmaster(a)domain.net protocols = imap lmtp sieve pop3 service auth-worker { unix_listener auth-worker { user = vmail } user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } user = vmail } service imap-login { inet_listener imap { port = 0 } service_count = 1 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } user = vmail } service pop3-login { inet_listener pop3 { port = 0 } } ssl = required ssl_cert =
