milter-reject: END-OF-MESSAGE

[L V Lammert (Omnitec Corp)]

Getting a weird error on a Mailsrv 4.7.6 system:

Oct 10 07:14:59 mail postfix/smtpd[25297]: AE9AE163472: client=ashley.domain.com[192.168.60.42], sasl_method=PLAIN, sasl_username=ag...@domain.com
Oct 10 07:14:59 mail postfix/cleanup[12273]: AE9AE163472: message-id=<52569A46...@domain.com>
Oct 10 07:14:59 mail postfix/cleanup[12273]: AE9AE163472: milter-reject: END-OF-MESSAGE from ashley.domain.com[192.168.60.42]: 4.7.1 Service unavailable - try again later; from=<ag...@domain.com> to=<l...@me.net> proto=ESMTP helo=<[192.168.60.42]>

Occurring randomly for more than one user this week, .. users have Thunderbird. Any possible causes?

    Thanks!

I had frequent problems with the milter hanging up and causing that problem in 4.8, so I ended up disabling and bypassing it. As yet I've not had any trouble with it in 5.3.
