smtpauth not working for me.

I have a problem using smtpauth from my ecommerce platform.

If I use mail.lakeservers.com I get an error:

warning: TLS library problem: error:14094415:SSL routines:ssl3_read_bytes:sslv3 alert certificate expired:ssl/record/rec_layer_s3.c:1544:SSL alert number 45:

If I use the server server.companiondriver.com  I get no error.  What is different about the two certs?

Edited to reflect grannydriver instead of lakeservers.

From postfix/main.cf:

# network settings
inet_interfaces = all
mydomain = yourdomain.com <--------------- does this matter? Seems like YES!
myhostname = server.companiondriver.com
mynetworks = $config_directory/mynetworks
mydestination = $myhostname = server.companiondriver.com
relay_domains = proxy:mysql:/etc/postfix/mysql-relay_domains_maps.cf

Your server is responding with domain "www.grannydriver.com", not "mail.grannydriver.com":

Code: [Select]

This suggests that you need to configure a additional certificate, for "mail.grannydriver.com", in addition to other domains you use.

I dont understand.   I have certs for all of my mail.domain.com websites, verified with ssllabs.com

So you have problem with SNI configuration in postfix.
Check you have the following configuration enabled in /etc/postfix/main.cf :

Code: [Select]

tls_server_sni_maps = hash:/etc/postfix/vmail_ssl.map
...and make sure all domains you have (included 'mail.grannydriver.com') in the file '/etc/postfix/vmail_ssl.map'.

The same logic is too valid for dovecot.
Check if you have the following, at the end of the file '/etc/dovecot/dovecot.conf':

Code: [Select]

!include_try /etc/dovecot/sni.conf
...and check the content of the file '/etc/dovecot/sni.conf' for your ssl domains.

The same logic is too valid for dovecot.
Check if you have the following, at the end of the file '/etc/dovecot/dovecot.conf':

Code: [Select]

!include_try /etc/dovecot/sni.conf
...and check the content of the file '/etc/dovecot/sni.conf' for your ssl domains.
