Unable to send or receive email after update - qq soft reject

After that, sending email failed with "unable to exec qq".


I saw that /etc/tcprules.d/tcp.smtp had
QMAILQUEUE="/var/qmail/bin/simscan"

simscan was missing, as yum had just removed it as part of the upgrade.

I tried installing simscan-toaster:

Your existing tcp.smtp file was *not* overwritten, but a new one was created called "tcp.smtp.new" that
you should look at to ensure no new directives were added that may cause issues with your system.

Some messages there didn't look good.

Now I get qq soft reject all the time in /var/log/maillog:
vps2 smtp: qmail-smtpd: qq soft reject (mail server temporarily rejected message (#4.3.0)):

These lines also look odd.
 vpopmail[2542]: vchkpw-smtp: vpopmail user not found uucp@<my dmomain>.co.uk:91.112.188.90

What can I do to get email working again?

[MRatWork]

Try 'sh /script/fixmail-all'

[tonym]

That didn't fix it.

I tried a /script/cleanup too.

[MRatWork]

From 'server mail settings', disable and then enable 'spamdyke', 'domainkey' and 'virus scan'.

[tonym]

Thanks. That didn't make any difference.


As a work-around, I edited the file /etc/tcprules.d/tcp.smtp, and changed
/var/qmail/bin/simscan     to    /var/qmail/bin/qmail-queue
Then:
qmailctl stop ; qmailctl cdb ; qmailctl start

Mail delivery then works, and spamdyke & bogo are still running on all my mail.

And I return it to use simscan for any testing.

[MRatWork]

Are you sure your IP not blacklist?.

[tonym]

I've checked my server in a blacklist search, and they all came up OK.

It is not listed in any of my spamdyke files.

The "qq soft reject" occurs for all incoming email as well, so it is not as if  only my server is being rejected.


My /etc/passwd file has a user "clam".  The installation of simscan-toaster came up with this message "warning: user clamav does not exist - using root". Could this result in a permission problem after /script/cleanup is run?

[MRatWork]

In latest simscan, I was change clamav to clam user because using 'pure' clamav (from epel) instead clamav-toaster (need compiled).
