While doing preliminary work to retiring a legacy proprietary email system, my own, looking at maybe setting up an IMAP server, just for the fun of it.
On a fresh openSuse 15.4 I see none installed by default and when I go sniffing about in YAST, i find several flavors available for install:
dovecot dovecot23 imap (and sundry)
Funny I was just ready about 3 body problems . . .
I think the choice is between dovecot and dovecot23, give what I have recently read, but find nothing that speaks to the difference between these versions.
I'm kicking hard but this swing is not moving, I may need a push.
Well, the votes are in. Selecting dovecot23 auto selects all the items with dove in the name. Isn't that special.
Hi Joe,
you may read https://en.opensuse.org/Mail_server_HOWTO to implement an e-mail system with all the modern protections. It covers postfix, dovecot, amavis- new, with malware scanning with clamav and spamassassin, SPL checking, DKIM checking and support for DMARC. I am working on a script to automate what has been written there and also to improve the mail module in YaST to be able to do the same as has been written in this openSUSE wiki page. It is meant for a server with only a few users, so a hobbyist or a small company. However you may use it as the basis for a larger server with all these security measures.
BTW, dovecot and dovecot23 are the same, but it is better to install dovecot using "zypper install --no-recommends dovecot", because you most like will not use a database to register the users, only the users registered in your computer.
In regard to the linked "how to" and "users registered in your system", which I expect to amount to only a few, I am unclear on how to create those users as "local" to that machine (the email server) where the mailboxes will exist for authentication purposes. In past lives, the user authentication always happened via other means, such as some LDAP directory or other "lookup table", accessible on some remote device, so never had to deal with native users for email purposes. In any case never before with dovecot. I'll keep plodding along, but someone may have quick insight. So far I get the equivalent of "go away, nasty person" when attempting to authenticate IMAP-ese via telnet.
