Good morning, I am running Exim 4.80 on Debian Wheezy.
I have setup a "maildrop" with Dovecot, Exim and Fetchmail, where an internal server fetches mail from external POP3 and IMAP servers, stores it locally and serves it over IMAP to local Samba4 AD users. So far it works great. Now, I am trying to setup an SMTP relay so those users can point their mail clients to this internal server in order to *send *mail. I have configured Exim with my ISP's SMTP server as a smarthost, and it works fine. The missing part is correctly handling the bounces in case the ISP's SMTP server is down, for example. *I need all mail coming in from the users' PCs via port 25 to be relayed to the external SMTP, regardless of their destination (even for addresses belonging to the local domain) *(since some mobile users access the external mailbox directly). Let's say my domain is foo.com. If I set foo.com as a local domain, then mail from [email protected] to [email protected] gets delivered locally and never reaches the external SMTP server (not what I need) If I don't set foo.com as a local domain, mail reaches the external SMTP and gets back properly, but if the external SMTP is down then the bounce goes nowhere (it is obvious since it doesn't know it is a local mailbox) How can I get those bounces to get locally delivered? I guess I need some way of specifying that foo.com needs to be considered as a local domain just for bounces, but regular mail to that domain needs to go through the external SMTP server. Thanks a lot George -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
