Hi,
I'm having trouble using Roundcube to send emails with my Virtualmin installation. Emails to other adresses inside my network work fine, but as soon as I try to send a Mail to, say, a gmail adress the following error message pops up:
SMTP Error (550): Failed to add recipient "myemail@gmail.com" (5.1.1 myemail@gmail.com: Recipient address rejected: gmail.com).
My 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

My Mail.log while trying to send the mail:
Jul 2 06:17:37 astra<censored> postfix/smtpd[7252]: connect from localhost[127.0.0.1]
Jul 2 06:17:37 astra<censored> postfix/smtpd[7252]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 550 5.1.1 <mymail@gmail.com>: Recipient address rejected: gmail.com; from=<me@myserver.TLD> to=<mymail@gmail.com> proto=ESMTP helo=<myserver.TLD>
Jul 2 06:17:37 astra<censored> postfix/smtpd[7252]: disconnect from localhost[127.0.0.1]
I found a few other threads with similiar problems, but in those cases it was due to blacklisting or a faulty user creation, hence the user not being found. I can't figure out what postfix is having trouble with in my case.
Edit 1: I was able to send a mail by commenting out default_transport = error relay_transport = error
Google page 3 to the rescue. Though I am not quite sure why a fresh installation would make problems.
Edit 2: It seems the mails never arrive at the destination. Checked my gmail and gmx account and they never received any mails from me.
Edit 3: gmail now accepts my mails after I fixed a typo in the main.cf: "smtp_sasl_auth_enable = yes" to "smtpd_sasl_auth_enable = yes"

I'll work on the PTR record. I wonder why a fresh install of virtualmin had these issues without me messing with any config.
