Hello,
msmtp stopped being able to connect to my SMTP server. It worked well
yesterday morning and the only thing that I did was a system update (I
did not change the client's or the server's config). Some info on my
system/config on the client's side:
$ uname -a
Linux K3PO 3.13-1-amd64 #1 SMP Debian 3.13.7-1 (2014-03-25) x86_64 GNU/Linux
$ cat ~/.msmtprc
defaults
tls on
tls_starttls off
auth on
logfile ~/.msmtp.log
syslog off
account damien
host smtp.desfontain.es
port 465
from dam...@desfontain.es
tls_certcheck off # I usually don't disable the certificate check, but
here, I just want to show that that's not the problem
user damien
passwordeval ******
$ msmtp-queue -r
msmtp: TLS handshake failed: An unexpected TLS packet was received.
msmtp: could not send mail (account damien from /home/damien/.msmtprc)
mail [ 2 ] [ 2014-05-01-09.24.59 ] from queue ; send failed ; msmtp rc = 76
$ tail ~/.msmtp.log
mai 01 09:36:07 host=smtp.desfontain.es tls=on auth=on user=damien
from=dam...@desfontain.es
recipients=d...@desfontain.es,dam...@desfontain.es errormsg='TLS
handshake failed: An unexpected TLS packet was received.'
exitcode=EX_PROTOCOL
and on the server's side:
$ uname -a
Linux smtp.desfontain.es 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux
# cat /etc/postfix/main.cf
[...]
smtpd_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
smtpd_tls_cert_file = /etc/postfix/tls/server.crt
smtpd_tls_key_file = /etc/postfix/tls/key.pem
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
smtp_tls_cert_file = /etc/postfix/tls/server.crt
smtp_tls_key_file = /etc/postfix/tls/key.pem
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtp_use_tls = yes
smtpd_tls_received_header = yes
smtpd_tls_ask_ccert = yes
smtpd_tls_loglevel = 1
tls_random_source = dev:/dev/urandom
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
I don't know if you need some additional info, don't hesitate to ask.
What seems really strage to me (and makes me think that the problem
comes from msmtp) is that when I test my SMTP authentication using a
tutorial such as this one:
http://rene.bz/setting-smtp-authentication-over-tls-postfix/
it works perfectly.
If someone has an idea of what could cause it, I would be really interested.
Best,
Damien
