1.

I expect exim should not add anything.
Per the discussion of the local_from_check config option: "An unqualified address (no domain) in the From: header in a locally submitted message is automatically qualified by Exim, unless the -bnq command line option is used"
Why exim doesn't add hostname in invocation with "-be"?
Because your expansion had no From: header to work with, and the only string left was the thing starting with an = that you explicitly gave it.
2. comma in addresses: # cat /tmp/test2 From: =?utf-8?B?YWFhYS1hYWFhLCBiYmJiYg==?= <[email protected]> # exim -bem /tmp/test2 '${addresses:$h_from:}' aaaa-aaaa:[email protected] Why exim sees two addresses? There is no literally coma, comma is encoded with base64. There is in doc "It does not see the comma because it’s still encoded as "=2C" ", so meseems it still shouldn't interpret comma also for base64
The doc sentence is discussing use of $rheader_from: - which is the Q-coded string. You used $header_from: - which has been decoded, so has a visible comma.
3. "-be" vs "-bem". The same header as above. # cat /tmp/test2 From: =?utf-8?B?YWFhYS1hYWFhLCBiYmJiYg==?= <[email protected]> # exim -bem /tmp/test2 '${addresses:$h_from:}' aaaa-aaaa:[email protected] vs # exim -be '${addresses:$h_from:From: =?utf-8?B?YWFhYS1hYWFhLCBiYmJiYg==?= <[email protected]>}' [email protected] Shouldn't be result of expansion the same in both cases?
No, for the multiple reasons described above. -- 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/
