Relay access denied when using SMTP to external recipients

That's normal. But this link might be interesting for you: http://www.howtoforge.com/block_spam..._level_postfix

Hi again,

I thought all was fine, but not quite! I had to reboot the server, and on running up, the directory /var/run/saslauthd is not there! I had to manually recreat it for SASL to work.

Why is this happening?

Thanks for your help.

Not sure why this is happening, but you could add the command to create that directory to /etc/rc.local.

OK, good idea - whilst I try to figure out why.

Thanks,

Andy

I have the same issue. Can't send to external recipients via mail client. I did enable smtp authentication in the mail client, which has no effect. But if I have smtpd_recipient_restrictions = permit_mynetworks permit_inet_interfaces permit_sasl_authenticated defer than I can send out fine, but than I can't get mail. Mail bounces saying For <user@domain.com>, Site (domain/xxx.xxx.xxx.xxx) said: 450 4.3.2 <user@domain.com>: Recipient address rejected: Try again later. I can't remove "defer" from smtpd_recipient_restrictions or postfix will fail to start. Any ideas?

What's in your mail log when you try to send a mail? What's in your main.cf? How did you set up your email account?

I am having a very perplexing issue and it is a 554 5.7.1 <xxxxxx@yahoo.com>: Relay access denied error.

I have been using the ISPconfig software for well over a year flawlessly …….. my business requirements changed and with that came the following……

Cisco 871 router
PIX 506e firewall
Windows Small Business Server 2003

I was using a Linksys BEF VPN router and everything ran fine (users authenticated against the linux box everything was super) ….. email worked from both inside and outside the network….. I added and configured the Cisco appliances and the SBS but I want to use ISPconfig for email until I receive more static IPs from my ISP to configure exchange and webmail (and everything else with SBS2003)…. Trouble began when the SBS2003 wanted to take over DNS which I thought at the time was fine but now from outside the network I can’t send email to anyone outside of our domain (I get 554 5.7.1 error)….. I just pass requests from FE4 (PPOE connection) through to the firewall, utilize NAT on the firewall and just translate the same ports from the old Linksys box…. I did notice the /etc/resolve.conf had the old private router IP so I added my SBS there (still no avail)……not even sure where to start……

Did you enable "Server requires authentication" in your email client?
What's in /etc/resolv.conf now?

Hi,

I've got the same problem. Via none of the domains hosted on this particular server (ubuntu - ispconfig) can mail be sent.

Authentication is set to on, using the same login details as pop. And on pop, all mail comes in.

I've attached a file with a lot of the info that has been asked by Falko in this thread to other people with similar problems.

p.s. I've got another problem too, being the Bind server showing as offline (although everything seems to work okayish), I don't know if that can have anything to do with it... I thought it'd be better if I make that another topic but I'll first see what people who know think of it.

Thanks, lex
