I've noticed mails being sent from my gmail account to a mailbox on a centos 7 server are not arriving their destination, but no bounce message returned as well.
This is what I've found in maillog:
Jun 1 14:59:26 myhost postfix/smtpd[31043]: warning: No server certs available. TLS won't be enabled
Jun 1 14:59:26 myhost postfix/smtpd[31043]: connect from mail-wi0-f176.google.com[209.85.212.176]

Jun 1 14:59:26 myhost postfix/qmgr[25681]: 5C764B61E54: removed
There is a self signed certificate on this server, and it used to work until today...
I've also added these lines to mail.cf - but it didn't help:
smtpd_tls_mandatory_protocols = !SSLv2,!SSLv3
smtpd_tls_protocols = !SSLv2,!SSLv3

It says sent, and delivered to command procmail-wrapper. Is there a log for procmail-wrapper? – golimar – 2015-06-03T13:09:21.487
It generates an error message and sends it to root@myserver.... – Dani – 2015-06-05T15:30:40.150
