I'm getting repeated email (KMail) error messages about one apparently over-large post: -------------------------- Received: from helen.gayleard.com (localhost.localdomain [127.0.0.1]) by helen.gayleard.com (Postfix) with ESMTP id E4500294A0 for <tim at helen.gayleard.com>; Sat, 24 Jan 2015 14:00:05 +0000 (GMT) Received: (from tim at localhost) by helen.gayleard.com (8.14.4/8.14.4/Submit) id t0OE02Ie006372; Sat, 24 Jan 2015 14:00:02 GMT Date: Sat, 24 Jan 2015 14:00:02 +0000 X-Authentication-Warning: helen.gayleard.com: tim set sender to root using - f From: Cron Daemon <root at helen.gayleard.com> To: tim at helen.gayleard.com Subject: Cron <tim at helen> /usr/bin/fetchmail -s mail.eircom.net fetchmail: SMTP error: 552 5.3.4 Message size exceeds fixed limit fetchmail: mail from MAILER-DAEMON at helen.gayleard.com bounced to biblioteca at comune.anghiari.ar.it -------------------------- I've appended mailbox_size_limit = 20000000 to /etc/posfix/main.cf (and re-started postfix) but this does not seem to have done the trick. I get this email by fetchmail, and it goes to dovecot from which I retrieve it on my laptop. So I'm not entirely clear where the problem occurs. I would delete the email if I could find it, but it does not appear to be in my Maildir, or in /var/spool/ . Is there some way I can stop these messages, please? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin
