Hi, I'm using Debian GNU Linux 6.0 "squeeze", postfix 2.7.1-1+squeeze1
I'm in need of using a smarthost to relay all of my mail. I'm unable to use an italia provider (aruba) as smarthos for my server. I obtain the (in)famous "550 5.1.0 XXXXX authentication failed" relevant part of logs: Feb 6 13:42:42 myserver postfix/smtp[12173]: > smtp.provider.com[ smtp.provider.com]:25: MAIL FROM:<r...@myserver.com> Feb 6 13:42:42 myserver postfix/smtp[12173]: < smtp.provider.com[ smtp.provider.com]:25: 550 5.1.0 x0ih1k00U1GKSXt010ihSY authentication failed Relevant part of configuration: relayhost = smtp.provider.com smtp_cname_overrides_servername=no smtp_sasl_auth_enable = yes #smtp_sasl_security_options = noanonymous smtp_sasl_security_options = smtp_sasl_password_maps = hash:/etc/postfix/sasl/saslpasswd smtp_always_send_ehlo = yes I've tested username/password using thunderbird as client, it works. I've tested the same configuration with another provider: it works. My guess is that the provider uses different server to answer to my request, and so postfix is unable to find a matching password in file /etc/postfix/sasl/saslpasswd. But I've tried by using smtp_cname_overrides_servername=yes or smtp_cname_overrides_servername=no and it failed in the same way. I've also tried to declare all hostnames that I can see in the logs placing all of them in the /etc/postfix/sasl/saslpasswd but even this way I cannot send my mail. Is there anyone that can help me? Thanks, larzeni
