My working mail config started failing after an upgrade to OpenBSD 7.2
and a pkg update.
# uname -a
OpenBSD bleh 7.2 GENERIC.MP#0 amd64
# pkg_info postfix
Information for inst:postfix-3.7.2p1-pgsql
postmap fails to do pgsql lookups. it crashes when attempting.
# postmap -q 'myemailaddress' pgsql:/etc/postfix/pgsql_virtual_mailbox_maps.cf
postmap(98686) in free(): bogus pointer (double free?) 0x80
Abort trap (core dumped)
# postmap -q 'myemailaddress' pgsql:/etc/postfix/pgsql_virtual_mailbox_maps.cf
Segmentation fault (core dumped)
I'm not sure why these were different.
I ran gdb and lldb on the core file and these were the results,
but I am new to these commands, so let me know if I can do better:
