I am using Qmail on a Unix system (Digital Unix) and recently had a
complaint from my customer that a new email user was unable to connect to
the system using Qmail. Evidently the user name needed to be upper and
lower case in their system and possibly in our server also.
Is Qmail RFC compliant with case sensitivity using mailbox user names? The
reason I ask is Qmail seems to take all user names to lower case. I have
heard through my peers that the RFC states that the mailbox user names need
to be accepted as either upper case or lower case and not be converted to
lower case. Is this true? If not would you say that Qmail is RFC
compliant? What is your thoughts with Qmail case sensitivity? Is there a
fix to the lower case conversion if I need to change our Qmail.
Bottom line is if it is not RFC compliant and there is not a fix to the case
sensitivity issue, then I might need to come up with a good argument not to
replace Qmail in our system.
Thank You
