You are correct. The docs do say something about this, though. From
section 39.19:
--------------------------------------------------------------------------------
Header lines that are added by an ACL at MAIL or RCPT time are not visible in |
string expansions in ACLs for subsequent RCPT commands or in the |
"acl_smtp_predata" ACL. However, they are visible in string expansions in the |
ACL that is run after DATA is complete (the "acl_smtp_data" ACL). This is also |
true for header lines that are added in the "acl_smtp_predata" ACL. If a |
message is rejected after DATA, all added header lines are included in the |
entry that is written to the reject log. |
|
If you want to preserve data between MAIL, RCPT, and the "acl_smtp_predata" |
ACLs, you can use ACL variables, as described in section 39.15. |
--------------------------------------------------------------------------------
There is a Wish List item to re-design and re-implement the way header
additions and substractions are handled in all the places in Exim that
this happens. But don't hold your breath.
