Hello. I know this topic has been discussed a lot. I'd like to convert
all incoming email addresses are converted to lower case.
Why?
I'm afraid this may break things like DKIM signatures.
I found the
following which Mr. Venema had posted.
/etc/postfix/main.cf
virtual_maps =
regexp:/etc/postfix/virtual_regexp
mysql:/etc/postfix/mysql-virtual.cf
/etc/postfix/virtual_regexp:
/^(.*[A-Z].*)$/ $1
It's a little disgusting, but I expect that it would work.
That's easily fixed - throw a @ somewhere in there:
/etc/postfix/virtual_regexp:
/^(.*[A-Z].*@.*)$/ $1
Two questions:
1. Is this still the best way to do this? The post I found is 20 years old.
2. I do not use any virtual maps currently and do not have a
/etc/postfix/mysql-virtual.cf . Will this
still work for me?
This will only work for envelope recipient addresses, it won't overwrite
header addresses not sender address.
