Presumably the network outage of your primary is keeping the secondary from reaching it for the callbacks. > The logs are full of the messages like these: > > unknown ACL verb "acl_check_mail" in "acl_check_mail" Sounds like someone's doubled a line somewhere, or otherwise pasted random junk into your Exim configuration. Search your exim.conf for that string, "acl_check_mail", it should occur exactly twice: 1. As the value of the acl_smtp_mail hook in the main config section 2. Followed by a colon, in the "begin acl" section, defining an ACL The third occurrence is probably where the problem lies (unless the second was the randomly pasted in junk). -Phil -- ## 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/
