Hi,

I'm building a Postfix/Dovecot mail server and while I am able to send/receive emails using telnet, after establishing a connection to Dovecot via a client (Mail Live, Thunderbird etc) the following appears in the logs:

Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3-login: Login: user=user@domain.com, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, mpid=282 78 Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.error] master: Error: service(pop3-login): child 28277 killed with signal 10 (core not dumped - set service pop3-log in { drop_priv_before_exec=yes }) Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3(user@domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/5, size=3250

I also experience very poor connectivity to the server, with Microsoft Mail and Thunderbird regularly failing to connect (connection errors in the client and no login attempt in the dovecot logs). I assume this is related to the issue above.

I am running dovecot 2.0.16 on Solaris 10 SPARC using a ZFS filesystem for mailbox storage.

Here is my configuration:

# 2.0.16: /usr/local/etc/dovecot/dovecot.conf # OS: SunOS 5.10 sun4u zfs auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:/storage0/home/vmail/%d/%n/Maildir mail_plugins = quota passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = maildir:User quota quota_rule = *:storage=1G } postmaster_address = root@domain.com sendmail_path = /usr/lib/sendmail ssl_cert =

I'm tearing my hair out! Hopefully someone can see something I'm missing
