I have a slight problem, and was curious what can be done to fix it.
I have a Cyrus/Postfix setup. It works great; however, we often receive
emails that don't match the case of the accounts on cyrus (all of them are
strictly lower case). In that event, postfix receives them OK, but cyrus
rejects them during LMTP negotiation.
Many of our clients are sending stuff using addresses that are using all caps
or title caps. These emails are being rejected by our system.
I totally understand that Cyrus and Postfix, for that matter, try hard to
adhere to standards (RFC, for example). However, business is business... and
we have to cater to our customers. Many of these customers are on Windows
systems, and don't have control (or knowledge, for that matter) of their mail
systems anyway.
Is there a workaround? Is there a setting for Cyrus that tells it to ignore
case? I'm also going to post to the postfix list also.
Any help would be most appreciated.
From my /etc/imapd.conf file:
# Forcing recipient user to lowercase
# Cyrus 2.1 is case-sensitive. If all your mail users are in lowercase, it is
# probably a very good idea to set lmtp_downcase_rcpt to true. The default is
# to assume the user knows what he is doing, and not downcase anything.
lmtp_downcase_rcpt: yes
