Phil,

Are you trying to find out how dovecot marks emails as unread?

Assuming you are using maildir format, it appears to be encoded as flags in the email filename on disk. 


It’s briefly covered in 'Filename examples'
https://wiki2.dovecot.org/MailboxFormat/Maildir

And in 'What can I put in info?'
https://cr.yp.to/proto/maildir.html

Every few years I try to work this problem out
User-Agent: Roundcube Webmail/1.4-rc1
please upgrade first


It is a long-standing problem and upgrading RCM is not a solution . .


- occasionally I would
like to re-mark a dir as having new mail so that the dir shows up as
blue-coloured in RCM.
please dont modify mails outside of imap protocol,


Then how do I do what I want with IMAP?


if you use
roundcube it will not be needed to mangle shell accounts


That comment doesn't make sense . .


Every time I Google in vain and then have a go
at working it out myself
if google have no answer to it, its simple not supported


Quite frequently not true . .


but the only thing I can see is that there is
a change in the appropriate dir dovecot.index.log file after having
the blue dir clicked on
dont mangle files outside of imap protocol


You already said that - what is your solution then?


(and the colour of the dir name changes back
to black) - so is the information stored somewhere in RCM itself?
no


OK, overall not a very helpful response . . but thanks anyway.
