Hostname error on my Slicehost Ubuntu server
- by allesklar
Like many folks who upgraded to Rails 2.2, I got an exception raised when sending an email. This version of Rails or later does require using tls for sending emails. The message in the production log file says:
hostname was not match with the server certificate
I did a whole lot of research and work on this and did everything I could. I changed my slice's hostname to ohlalaweb.com. If I run the command 'hostname' at the CL I get:
ohlalaweb.com
Postfix seems to work fine. I can send emails from the CL to my gmail, yahoo, and google apps gmail accounts with no problems. Here is the result of cat /etc/postfix/main.cf
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
myorigin = /etc/mailname
smmtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings

myhostname = ohlalaweb.com

alias_database = hash:/etc/aliases
mydestination = localhost.localdomain, localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
I have regenerated the ssl keys with the ohlalaweb.com host name.
Any ideas or suggestions?
