Mailer daemon: user unknown
Symptom:
In e-mails to an user comes only a mailer daemon's user unknown
, although everything seems to be correctly configured and
the user is in /stc/passwd.
Cause:
The user's name contains one or more capital letters. Here it is
first made the conversion into small letters (in e-mails the
small/capital writing must be the same) and afterwards is checked,
whether the user is in /etc/passwd
or not.
Solution:
It has been long discussed, whether this is a bug or not. Firstly
we will invest few time, to repair it because it is
extremely unusual (up to now only one person has reported it).
Change the loginname into small letters!
Stephan Hegering (sh@leverkusen.netsurf.de) writes
about it:
You must edit /etc/sendmail.cf ;-)
At the appropriate mailer in this mailer specification, add an u at the
flags (F=...). Hint,look for electric after "Mlocal,".
F=u --> Preserve uppercase for username
Otherwise the address's userteil is converted into lowercase.
This tip is not mine, but Dieter Brueggemann's
(Bert@stud-mailer.uni-marburg.de)
Hint: do not forget to set afterwards in /etc/rc.config
SENDMAIL_TYPE=no
, with this, /etc/sendmail.cf
is not overwritten again.
