Hi there. Is it possible to have hybrid mail systems with some users on courier and some on another mail server for the same domain?
I have a domain handled by Google Apps (gmail). Some of the users in that domain want to use a legacy mail server (courier) instead of google, so I would need split delivery, as documented by google (https://support.google.com/a/answer/119008): <quote> If some users use Gmail and others use their legacy accounts, you can have mail delivered to a Gmail account or a legacy mail account depending on the recipient. This option is called split delivery... </quote> So I'm ending up with a domain where non existent email addresses in google are routed to my custom courier server (https://support.google.com/a/answer/173534 -> directly to my courier ip, no mx record). My problem is: if I add this domain as locally-hosted domain, people using courier cannot send mails to other people of the same domain running in google apps. Example: - mx for mydomain.com points to google; - us...@mydomain.com is defined in google; - us...@mydomain.com is defined in courier; - google is configured for split delivery, routing mails for us...@mydomain.com to courier; - us...@mydomain.com (courier) wants to write a mail to us...@mydomain.com (google). It FAILS because us...@mydomain.com does not exists (because is defined in google). So, I'm trying to do the reverse, handling split delivery on courier, but I cannot find a good way to do this. The only solution I've found is: 1- create all users for this domain in courier 2- point the mx record to courier to receive mails 3- write some maildrop rules to forward desired mails to google via an external mta xfilter (because maildrop cannot forward mails to custom smtp servers without using mx records). Is there a better way?
