I recently found this in an old exim config: ########################################################################### # Deny if the local part contains @ or % or / or | or !. These are # rarely found in genuine local parts, but are often tried by people # looking to circumvent relaying restrictions. # Also deny if the local part starts with a dot. Empty components aren't # strictly legal in RFC 2822, but Exim allows them because this is # common. # However, actually starting with a dot may cause trouble if the local # part is used as a file name (e.g. for a mailing list). deny local_parts = ^.*[@!/|] : ^\\.
Is this config still relevant? I couldn't think of any way of how to circumvent relaying restrictions by using special characters. -- ## 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/
