I have Dovecot server from a iRedMail install, version 2.0.21

dovecot --version 2.0.21

yum update wants to update as so from iRedMail repo:

--> Running transaction check ---> Package dovecot.x86_64 1:2.0.21-0_136.el6 will be updated ---> Package dovecot.x86_64 1:2.1.17-0_136.el6 will be an update ---> Package dovecot-managesieve.x86_64 2:0.2.6-22.el6 will be updated ---> Package dovecot-managesieve.x86_64 2:0.3.6-26.el6 will be an update ---> Package dovecot-pigeonhole.x86_64 2:0.2.6-22.el6 will be updated ---> Package dovecot-pigeonhole.x86_64 2:0.3.6-26.el6 will be an update --> Finished Dependency Resolution

Updating:

dovecot x86_64 1:2.1.17-0_136.el6 iRedMail 2.4 M dovecot-managesieve x86_64 2:0.3.6-26.el6 iRedMail 45 k dovecot-pigeonhole x86_64 2:0.3.6-26.el6 iRedMail 348 k

so, if I run this update, I'll update to '2.1.17-0', yes ?

ahem, dumb question ahead: what's the '1' in front ? 1:2.1.17-0_136

(dumb user worrying that I don't attempt to install ver 1...)

apart from /etc/dovecot/*, should I backup anything else ?

sorry for dumb q...

thanks
