Hi Albert, I’d recommend upgrading, 2 major releases behind. (Latest 3.4.1). Running old software isn’t recommended but it’s a risk based decision on your part and specific to your environment and security posture.
Id suggest having a look at known security vulnerabilities for Cyrus (link below). Although the version may match known issues, doesn’t mean it’ll be exploitable. Configuration generally plays a part in determine exploitability. https://www.cvedetails.com/vulnerability-list/vendor_id-1321/Cyrus.html Hope this helps, Andrew Sent from my iPhone > On 18/06/2021, at 00:10, Albert Shih <[email protected]> wrote: > > Hi > > I would really like to know how often you upgrade (major) the version you > cyrus-imap. > > I'm undecided if I should run my cyrus 3.0.x until the end of the hardware > (3 years from now). > > I don't really need anything more than what I already have in term of > feature. > > And is it easier to upgrade each time a major release was release or it > don't change lot of time. > > Regards > > -- > Albert SHIH > Observatoire de Paris > xmpp: [email protected] > Heure local/Local time: > Thu Jun 17 02:06:37 PM CEST 2021 ------------------------------------------ Cyrus: Info Permalink: https://cyrus.topicbox.com/groups/info/T1b7cba8d7073707a-M52a70deb379d9962268e94de Delivery options: https://cyrus.topicbox.com/groups/info/subscription
