Hello,
armel is little-endian (More details here:
https://wiki.debian.org/ArmEabiPort ), the handling of misaligned accesses
seems to be configurable but fgive garbled results by default:
https://wiki.debian.org/ArmEabiFixes#word_accesses_must_be_aligned_to_a_multiple_of_their_size

>> a rewriting rule is found

Yes, this is exim rewriting:
--------------------
*@+local_domains "${lookup{${local_part}}lsearch{/etc/email-addresses}\
                   {$value}fail}" Ffrs
# identical rewriting rule for /etc/mailname
*@ETC_MAILNAME "${lookup{${local_part}}lsearch{/etc/email-addresses}\
                   {$value}fail}" Ffrs
--------------------


I will ask the bug submitter to add the missing reponses directly here.
