Topic: SMTP TLS SSL error

Hi. I'm using Debian 6 Squeeze, iRedMail v0.7.4 and MySQL. I'm trying to setup the SMTP configuration on my email client to be able to send emails.

So far, here is what I have in the SMTP account details configuration:
Server name: mailit.machinary.it
Port: 465
User name: www@machinary.it
Auth: password
Connection: SSL/TLS

But every time I try sending emails, my email client pops up an error.

A glance at the /var/log/mail.warn log seems like it's a problem with SSL:

Mar 26 16:54:32 mailit postfix/smtpd[873]: warning: TLS library problem: 873:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1102:SSL alert number 48:

Mar 26 16:55:23 mailit postfix/smtpd[873]: warning: TLS library problem: 873:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1102:SSL alert number 48:

Is this problem related to my SSL cert? How can I fix it?

Thanks,
--b

Re: SMTP TLS SSL error

You should use below settings instead:

Server name: mailit.machinary.it
Port: 587
User name: www@machinary.it
Auth: password
Connection: STARTTLS
