I followed this guide in setting up email on 10.10 and upgraded to 11.04 when it came out with no issues. The 11.10 upgrade caused all sorts of mishaps for sending email by smtp and receiving.

SMTP:
My SMTP server does not support LOGIN. I've telnetted in and it is not listed.

Dovecot

Sending mails to any of the addresses bounces back with the following error:

Code: The mail system

<croxis@nimbus.croxis.net> (expanded from <david@davidradford.name>): command
   line usage error. Command output: /usr/lib/dovecot/deliver: invalid option

I'm not sure what the relevant configs would be to diagnose this. Thank you for any help at all!

This sounds a lot like bug 875440... there's a temporary workaround to try there. Might be worth adding your information to the bug report. Bonus points if someone can figure out what's broken and produce a patch, so that it stops being broken.

[hoopycat]

Correction: you might actually have two problems there. The bouncing problem seems to be due to the -n option on the deliver command line. Try removing it?

[croxis]

I fixed the dovecot issue by removing -n and downgraded according to the fix in the bug bug report. However I am still having the same issue in sending emails which is why I think it might be a configuration issue I am not seeing. Here is my ehlo:

Code: 250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

thanks! I solved my problem reading this thread.

I had upgraded from Ubuntu 11.04 to 11.10 and I did not receive my local email.
Then I see this line in /etc/postfix/main.cf:
Code: mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/conf.d/01-mail-stack-delivery.conf -n -m "${EXTENSION}"

Then I removed the "-n" option , restart postix and it works again!
