Hi,
though this is a bit of a side question, has anybody had an issue while running Outlook 2010 with Dovecot?
The reason why I am asking is that I have setup a Dovecot 2.1.7 server on FreeBSD which works fantastically with Thunderbird but Outlook seems to be twice as slow in transferring information across??
# dovecot -n # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE amd64 auth_debug = yes auth_mechanisms = plain ntlm login auth_use_winbind = yes auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_gid = mail_user mail_home = /mail/AD_Mail/%Ld/%Ln mail_location = maildir:~/Maildir mail_uid = mail_user passdb { args = failure_show_msg=yes driver = pam } pop3_fast_size_lookups = yes pop3_lock_session = yes pop3_no_flag_updates = yes protocols = imap pop3 ssl = no userdb { driver = static }
Since (like most corporate organizations out there) we solely run Outlook coupled to Exchange, this excersize was meant to be a way of getting rid of PST files. We don't run out own Exchange however, and don't have any control over it either.
My workaround was to simply use the Outlook GUI space to transfer emails between Exchange and Dovecot running the IMAPv4 protocol.
For whatever reason Outlook is being really garbage about dealing with stuff and since I don't know Outlook or MS products very well (being your typical average OpenSource guy) I was wondering if there were any tweaks that could be made within Outlook to speed it up or in Dovecot to work better with Outlook?
I guess one could get sidetracked into the argument of mdbox vs. Maildir from my config however, Thunderbird is really fast and transfers large amounts of data really easily. Reaches round 130Mbps using nload performance grapher, while Outlook only manages ~50kbps but spikes at 2-3Mbps on occassion.
Try to understand (from dovecot logs) if there are difference between outlook and thunderbird, for example outlook connect over ssl and thunderbird no ecc..

Hi Nicola,
there is no specific difference apart from seeing many of these errors:
