    Angry Zimbra does not support upper-case letters in an email address?

    I have an email account set up for a project, "project@company.com".

    Sometimes customers will send us an email to Project@company.com and the email will get rejected for "Invalid Address". Really? If Zimbra cannot handle upper-case letters, why does it not resolve the address as being in all lower-case rather than reject the email outright? PrOjECt@company.com should work.

    Email addresses are case insenstive, and I've tested it on my Zimbra 8 install with the expected results. Maybe maybe they are using Zero instead of Oh.

    No, it should not work. Zimbra is RFC compliant and the relevant RFC2181 says this:

    RFC 2821, the standard that defines how email transport works, lays down the email address case sensitivity issue thus:

    The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. Mailbox domains are not case sensitive. In particular, for some hosts the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged.
