Good day to everybody! ;) My FreeBSD 10.1-RELEASE-p13 amd64 can't send email to localhost anymore! I know that openssl has been updated, and it raises the bar of bit size of dh parameters. I know, there is an update for sendmail to catch up it. But. it didn't help. Here is one of my servers. I did not touch anything in /etc/mail after installation of my system. And of course I didn't create a dh parameters in /etc/mail/certs dir. root at pyxis-v:~ # freebsd-version 10.1-RELEASE-p13 root at pyxis-v:~ # echo test | mail -s 'aa' ptimofeev at ocs.ru root at pyxis-v:~ # tail -f /var/log/maillog Jun 18 11:19:00 pyxis-v sendmail[1122]: t5I8J0F1001122: from=timp, size=39, class=0, nrcpts=1, msgid=<201506180819.t5I8J0F1001122 at pyxis-v.ocs.ru>, relay=root at localhost Jun 18 11:19:00 pyxis-v sendmail[1122]: STARTTLS=client, error: connect failed=-1, reason=dh key too small, SSL_error=1, errno=0, retry=-1 Jun 18 11:19:00 pyxis-v sm-mta[1123]: STARTTLS=server, error: accept failed=0, reason=sslv3 alert handshake failure, SSL_error=1, errno=0, retry=-1, relay=localhost [127.0.0.1] Jun 18 11:19:00 pyxis-v sendmail[1122]: ruleset=tls_server, arg1=SOFTWARE, relay=[127.0.0.1], reject=403 4.7.0 TLS handshake.

No changes in /etc/mail since installation. What's going on? So looks like everybody who updated their systems to p-1(2|3) has to do some stuff (openssl dhparam -out dh.param 2048). IMO, it's really, really bad. Am I wrong, misunderstanding or doing something wrong?
Here is kind of proof that nothing is changed in mail dir since installation. root at pyxis-v:~ # ll /etc/mail total 384 -rw-r--r-- 1 root wheel 6814 Oct 7 2014 Makefile -rw-r--r-- 1 root wheel 2900 Oct 7 2014 README -rw-r--r-- 1 root wheel 632 Oct 7 2014 access.sample -rw-r--r-- 1 root wheel 1691 Oct 7 2014 aliases -rw-r----- 1 root wheel 131072 Aug 6 2014 aliases.db drwxr-xr-x 2 root wheel 512 Aug 6 2014 certs/ -rw-r--r-- 1 root wheel 58400 Oct 7 2014 freebsd.cf -rw-r--r-- 1 root wheel 4537 Oct 7 2014 freebsd.mc -r--r--r-- 1 root wheel 40741 Oct 7 2014 freebsd.submit.cf -r--r--r-- 1 root wheel 898 Oct 7 2014 freebsd.submit.mc -r--r--r-- 1 root wheel 5659 Sep 15 2014 helpfile -rw-r--r-- 1 root wheel 405 Oct 7 2014 mailer.conf -rw-r--r-- 1 root wheel 248 Oct 7 2014 mailertable.sample -rw-r--r-- 1 root wheel 58400 Oct 7 2014 sendmail.cf -r--r--r-- 1 root wheel 40741 Oct 7 2014 submit.cf -rw-r--r-- 1 root wheel 574 Oct 7 2014 virtusertable.sample root at pyxis-v:~ # ll /etc/mail/certs/ total 12 lrwxr-xr-x 1 root wheel 10 Aug 6 2014 6ba511ab.0@ -> cacert.pem -rw-r--r-- 1 root wheel 1285 Aug 6 2014 cacert.pem -rw-r--r-- 1 root wheel 1334 Aug 6 2014 host.cert -rw------- 1 root wheel 1704 Aug 6 2014 host.key 2015-06-18 11:34 GMT+03:00 Pavel Timofeev <timp87 at gmail.com>:> Good day to everybody! ;) > My FreeBSD 10.1-RELEASE-p13 amd64 can't send email to localhost anymore! > > I know that openssl has been updated, and it raises the bar of bit > size of dh parameters. > I know, there is an update for sendmail to catch up it.
