[...] We have a well-established different convention which subdivides this, based on the last two digits of the uid: "/var/spool/mail/12/fred" (for fred's uid as something ending "[...]12"). This is working nicely with dovecot, using the new rc7 functionality: default_mail_env = mbox:%h:INBOX=/var/spool/mail/%-2.02i/%u:[...]
I am now trying to get sendmail to use dovecot's "deliver" as the LDA, [...] The main problem is that, according to the log file, the delivery attempt is being made to an INBOX "/var/spool/mail//fred". That is, it seems to be ignoring the "default_mail_env" setting.
Have I missed something in the wiki, or is this a bug of some sort?
I have looked deeper at my problem (abov). It seems to be a bug in rc7, and probably an "always been there" bug.
I sprinked a few "i_info(...)" diagnostics into "deliver.c" where it does 'getenv("MAIL")' and 'getenv("DEFAULT_MAIL_ENV")'. It shows that these are being successfully read from the 'dovecot.conf' file (good).
But, crucially, it seems that the "%" variable substitution is incomplete:
line 483: MAIL [null] line 486: MAIL mbox:%h:INBOX=/var/spool/mail/%-2.02i/%u:INDEX=/var/spool/mail/indexes/%d/%n line 492: MAIL mbox:/home/fred:INBOX=/var/spool/mail//fred:INDEX=/var/spool/mail/indexes//fred
(Aside: The act of inserting the 'i_info' will have knocked the line numbers adrift by a couple. But it shows what is (not) happening.)
Note in the "INBOX=..." clause that while "%u" and "%h" have been successfully expanded (good), the "%i" variant (UNIX uid) has failed to get expanded (bad).
I'm new to dovecot, so am on a steep learning curve and am unfamiliar with the source code and dovecot's principles. So it would probably take me ages to work out a suitable patch, and even then it might be inappropriate.
But hopefully the above information is sufficient and suitable for someone (Timo?) to investigate more expertly and fully.
If someone can produce a patch (or hints of what to patch and where) I would certainly intend to test it and work on it for you.
Hope that helps. Many thanks in advance.
