Sending mail using SMTP does not work (SASL error)

[Mannekino]

I'm trying to send e-mail from my server. I followed this tutorial and everything seems to be working fine except for sending e-mail.

My ISP doesn't allow traffic over port 25 so I put the following line in the master.cf file. I'm running the latest version of Ubuntu with ISPConfig 3.0.3.

2525      inet  n       -       n       -       -       smtpd

This is the error message I get:

Nov 21 12:36:44 vm1 postfix/smtpd[2202]: connect from xxx.direct-adsl.nl[xxx]
Nov 21 12:36:44 vm1 postfix/smtpd[2202]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory
Nov 21 12:36:44 vm1 postfix/smtpd[2202]: warning: SASL authentication failure: Password verification failed

Nov 21 12:36:44 vm1 postfix/smtpd[2202]: warning: xxx.direct-adsl.nl[xxx]: SASL LOGIN authentication failed: generic failure

Now I found this topic in where the same problem is addressed. This person said that he uncomment the following line in the master.cf file. I tried the same but it did not work for me, like this.

submission inet n       -       -       -       -       smtpd

I also tried removing the -c flag in the saslauthd file. Like somebody suggested in that topic. But that also did not work.

Output of ps aux | grep sasl

Anybody got a solution for my problem?

Thank you for your help.

I fixed the problem by changing:

2525      inet  n       -       n       -       -       smtpd

to

2525      inet  n       -       -       -       -       smtpd

It must run in chroot. I found the following article:
