https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200903 Xin LI <delphij@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |delphij@FreeBSD.org Assignee|freebsd-bugs@FreeBSD.org |re@FreeBSD.org --- Comment #1 from Xin LI <delphij@FreeBSD.org> --- We are aware of this issue and there will be an EN to correct this. In the meantime, please use this workaround: 20150614: The import of openssl to address the FreeBSD-SA-15:10.openssl security advisory includes a change which rejects handshakes with DH parameters below 768 bits. sendmail releases prior to 8.15.2 (not yet released), defaulted to a 512 bit DH parameter setting for client connections. To work around this interoperability, sendmail can be configured to use a 2048 bit DH parameter by: 1. Edit /etc/mail/`hostname`.mc 2. If a setting for confDH_PARAMETERS does not exist or exists and is set to a string beginning with '5', replace it with '2'. 3. If a setting for confDH_PARAMETERS exists and is set to a file path, create a new file with: openssl dhparam -out /path/to/file 2048 4. Rebuild the .cf file: cd /etc/mail/; make; make install 5. Restart sendmail: cd /etc/mail/; make restart A sendmail patch is coming, at which time this file will be updated. -- You are receiving this mail because: You are the assignee for the bug.
