I assumed that you were blocking the pair (src ip 46.148.40.108, target port 25) and was checking that you are also blocking (src ip 46.148.40.108, target port 465)Could this cause a 601 error?
Possibly a typo? SMTP does not define any 6xx error code. Also, irrelevant. Blocking done by a firewall would be stopping TCP-level connection, so you won't get any SMTP communication at all. How a client reports that is up to it. -- Cheers, Jeremy -- ## 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/
