[Dovecot] retr errors
My ISP uses Dovecot and I have had an ongoing problem for a while using several email clients. Sometimes the response to a retr request is mal-formed. The expected response +OK nnn octets is not returned. The response looks like it started somewhere in the message headers. Sometimes a retry can clear the problem but I usually need to delete the first message via a putty session. The problem, when present, is always on the first message. Never seen it in the middle of a series of messages. This problem has been seen on different machines, different versions of Windows, at home and on the road. I have wireshark traces showing good and bad sessions == stat +OK 93 1000437 retr 1 +OK 6946 octets Return-path: . = retr 1 of blahb...@blah.com designates 2607:f8b0:4001:c03::235 as permitted sender) smtp.mail=blahb...@blah.com; dkim=pass header.i=@blah.com Reply-To: android-develop...@googlegroups.com Precedence: list Mailing-list: .. == My ISP has been non-helpful. Any ideas how I can track down the problem? Thanks Bill
Re: [Dovecot] retr errors
Hi Bill You should send the wireshark traces to your ISP and ask him to fix it. At least one would require the doveconf -n output and the version of dovecot. Probably a bug in an older dovecot version? Regards Daniel

Hi Bill, any intercepting virus scanner or personal firewall software between your mail client and the dovecot server? Regards Daniel
