Hi All, I've been having issues where emails are being rejected by Cyrus because the "From" address contains an underscore in the domain name.
Example address: u...@lists_example.org What I am looking for is a way to parse email addresses and replace all underscores to dashes, eg. the following: u...@lists_example.org -> u...@lists-example.org I don't mind if I can't send emails to the actual person, but it's difficult to follow mailing list conversations if some of the replies are missing. I've been trying to figure out how it works, but I'm not sure where to put the regular expression for this. Or is there a flag I can set in the configuration to do this automatically? Many thanks for your help, Joost PS. I have contacted the domain admins where these are coming from, but I'm not convinced the user is actually using their smtp-server for outbound emails.
