Dovecot v1.0.15 Installation

Build the oldest version with the hope that it can handle old storage structure. Downloaded the source code from https://www.dovecot.org/releases/1.0/dovecot-1.0.15.tar.gz and built it following the instructions:

./configure --enable-static
make

Installation steps:

• Unzip dovecot.zip in /opt

chown 1205:1205 /opt/dovecot

• Create user/group dovecot/dovecot 1205/1205 with home in /opt/dovecot

groupadd -g 1205 dovecot
useradd -m -d /opt/dovecot/home/dovecot -g 1205 -u 1205 dovecot
su - dovecot
mkdir -p /opt/dovecot/home/dovecot

• The uid/gid/password of the main (and only) IMAP user are built into conf/passwd and conf/userdb, and they're also referred from the conf file (first_valid_uid/last_valid_uid). No OS-level user needs to be created, just we need to make sure there's no uid/gid conflict.

• Update /opt/dovecot/conf/userdb with the user's home. As root:

mkdir -p /opt/dovecot/home/ovidiu
chown -R 58285:58285 /opt/dovecot/home/ovidiu

then update /opt/dovecot/conf/userdb.

• Start/stop:

cd /opt/dovecot
./start-dovecot|./stop-dovecot

• Restore Maildir, link it from /opt/dovecot/home/ovidiu and

chown -R 58285:58285 /opt/dovecot/home/ovidiu/Maildir
