Such a mail may be a test message that user sent to its own address. So blind comparison of From: and To: is not a good idea, especially taking into accout that To: can contain several destination addresses and may be used as Cc: field to keep own copy of outgoing mail. Take a look at DMARC. -- Eugene Berdnikov -- ## 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/
