| Summary | 0011749: On Rocky Linux 10.1, the postfix package (postfix-3.8.5-8.el10.x86_64) was built against OpenSSL 3.2.x headers | ||||
| Description | ### Summary On Rocky Linux 10.1, the postfix package (postfix-3.8.5-8.el10.x86_64) was built against OpenSSL 3.2.x headers but at runtime uses OpenSSL 3.5.1, causing: warning: run-time library vs. compile-time header version mismatch: OpenSSL 3.5.1 may not be compatible with OpenSSL 3.2.0 This warning appears each time SMTP/TLS is negotiated in Postfix logs. | ||||
| Steps To Reproduce | ### Steps to Reproduce 1. Install Rocky Linux 10.1 2. `dnf -y install postfix` 3. Send inbound mail 4. Observe warning in `/var/log/maillog` ### Current Behavior Postfix logs a runtime warning about OpenSSL header vs library mismatch. -- log extract: Jan 18 16:14:31 ----------- postfix/smtpd[16344]: warning: run-time library vs. compile-time header version mismatch: OpenSSL 3.5.0 may not be compatible with OpenSSL 3.2.0 Runtime TLS negotiation still succeeds (e.g., TLSv1.3 + strong ciphers), but the warning may indicate potential ABI compatibility issues. | ||||
| Additional Information | ### Expected Behavior The postfix package should be built against the same OpenSSL version that ships with the OS (3.5.x) to avoid version mismatch warnings. ### Environment $ cat /etc/os-release Rocky Linux release 10.1 (Blue Onyx) $ rpm -q postfix openssl openssl-libs postfix-3.8.5-8.el10.x86_64 openssl-3.5.1-5.el10_1.x86_64 openssl-libs-3.5.1-5.el10_1.x86_64 $ openssl version OpenSSL 3.5.1 1 Jul 2025 | ||||

I should have added: - `dnf distro-sync` shows all packages up-to-date - TLS is otherwise functioning normally |
