Apologies if this has been discussed before. I have a number of clients with mailboxes on my server who are complaining that they are losing important incoming emails. On further investigation, this turns out to be caused by the senders incorrectly capitalising the username. Is there a plugin or patch for qpsmtpd to make it force all account names in incoming email to lowercase?
Could you provide more details on where the problem lies? i.e where is the mail bouncing?
The localpart of the address is defined as case-sensitive until the mail is handed to the local delivery agent. Most MDAs are case-insensitive, but gateways to other mail systems cannot assume that downstream mail systems are.
IMO the case MUST be preserved when passing through qpsmptd, and all qpsmtpd plugins SHOULD perform tests in a case-insensitive manner unless they have a specific reason for performing a case-sensitive test.
Thanks, Gordon
