A bit of reading uncovered a potential problem - the site uses firstname.lastname@domain, and I have come across references that Cyrus does not support this. I couldn't find this limitation in the Cyrus documentation.

Is it true?

Hmm. Do you need it as >username<? You could create usernames as firstname_lastname@domain and use the virtusertable to map firstname.lastname@domain to the loginname using the '_'.

Another posibility would be to use LDAP... Harder...

And yet another posibility (taken from man imapd.conf):

unixhierarchysep: 0 Use the UNIX separator character '/' for delimiting levels of mailbox hierarchy. The default is to use the netnews separator character '.'.

Oliver, Thanks All I need to do is maintain email address format firstname.lastname@domain, I do not need these as either unix/windows(samba) usernames. Currently these are a mixed bag of firstname, initiallastname & lastname. One step on the migration is to at least standardize the new ones.

Any suggestions on whether we'd be better off operationally using ldap to control the mapping or the virtusertable. It is a smallish site (<50 users), who are looking for a very automated administrative/operations environment.

This is my first cyrus so what I don't know is everything :-)

Than simply use virtusertable (if you use sendmail, or whatever is postfix equivalent if you use postfix) to map email addresses in first.last@domain format to actual usernames. This is kind of standard thing to do, and I'm surprised you haven't done it that way while you were on courier too.

Quoting Dave Hornford OSD@HOrnfordAssociates.com:

Its the result of reading something about an app I know nothing about and attempting to head-off a problem before I get there. In retrospect what I read, and the follow-up google searches that showed there might be a problem, were from people who knew less than I did. But that is the internet - help files and directions written for people who know what to do, and help queries from the lost, who don't even know what terminology to use when asking for help.

My guess is that what you found on the web were problems with usernames containing dots. Not email addresses containing dots. If users have usernames as you described (with no dots), you should be fine. Translation from first.last@domain to usernames is most likely done at MTA level, whatever they used for MTA. If they used sendmail or postfix, you probably won't have any additional work to do. If they used Courier's MTA module, you'd need to replace that with either sendmail or postfix and create table with mappings between email addresses and usernaems (either using aliases or virtusertables).

Sebastian allready said what there is to say 'bout Cyrus. :-)

There's no need to use LDAP for such a small site, if you don't want to grow very much or there are really good reasons. :-)

If you don't need the loginnames as first.last@domain, then you're better off with not using unixhierarchysep, as the normal way using the netnews seperator is really good tested. :-)

So long, Oliver
