So RFC's 821, 822, 2821, and 5321 all explicitly state that local-parts are case-sensitive and RFC's 2822 and 5322 say it indirectly by way of the ABNF spec. The one exception is postmaster, which gets special treatment as the only address that has to exist in every domain. Note that the transport and header case-sensitivity does not automatically translate into how delivery agents and mailstore agents work. In this case, the case-folding is being done by Postfix's local component, which is its documented behavior.

[Dovecot] Address Extensions with System Users
I am using Dovecot 1.2RC2 with Postfix 2.5.5. Everything is running fine. I would like to start using address extensions and have e-mail automatically filtered into folders based on the folder name after the + in the e-mail address. I only use system users, no virtual users. I have Deliver configured in main.cf as: mailbox_command = /usr/local/libexec/dovecot/deliver Everything I can find about setting this up applies to virtual users which I do not have. How do I get Deliver to recognize the address extension. I am sure it is easy, and I apologize for not finding the answer out myself.

Well doesn't that suck. I have no idea how to create a wrapper script. I guess I need to figure something else out. So, if I was create virtual users I would be able to use the +ext filter method?

No idea if you can change it. Thanks for your help. I have left a message on the postfix list to see if they can help with the lowercase issue. I seem to be getting two messages for any e-mail that has the plus addressing in it. Is this a Deliver problem or a Postfix problem? Where would I start to troubleshoot it? Jeff
