Hello Exim Community, I am encountering a consistent issue with Exim 4.98 during DKIM signing of outgoing messages. The system throws a SIGSEGV fault when trying to open the DKIM private key for a specific domain.
Environment Details: Exim version: 4.98 (installed via DNF package) DKIM Setup: DKIM keys generated with OpenSSL (RSA, 2048-bit) and located in /etc/exim/dkim/ Permissions: /etc/exim/dkim/ directory: drwxr-x--- owned by root:exim my_domain_rsa.private key file: -rw-r---- owned by exim:exim Error Summary: During the signing process, Exim attempts to read the DKIM private key and throws a segmentation fault. Below is the relevant log excerpt: 2024-09-19 22:20:47.648 [102824] 1srHd6-00000000QJ2-29NT backtrace 2024-09-19 22:20:47.648 [102824] 1srHd6-00000000QJ2-29NT exim(stackdump+0x34) [0x55f37381aa84] 2024-09-19 22:20:47.648 [102824] 1srHd6-00000000QJ2-29NT exim(+0x77c1e) [0x55f37381ac1e] 2024-09-19 22:20:47.648 [102824] 1srHd6-00000000QJ2-29NT unable to open file for reading: /etc/exim/dkim/my_domain_rsa.private 2024-09-19 22:20:47.648 [102824] 1srHd6-00000000QJ2-29NT SIGSEGV (null pointer indirection) Steps Taken So Far: Rechecked permissions: Both the directory and the private key have the correct permissions (exim user has access). Key integrity: Verified that the RSA private key is valid using openssl rsa -in /etc/exim/dkim/my_domain_rsa.private -check. Debugging: Enabled Exim debug logging (exim -d+all -qff) and confirmed the process crashes specifically during key access. Tried Re-Generating Keys: Same result with newly generated keys. Tried Reinstalling Exim: Uninstalled and reinstalled Exim but the issue persists. Has anyone else encountered this issue, or is there something I may have missed in configuring DKIM support in Exim 4.98? Thank you for any insights!
