Many thanks to Joseph Tam and Steffen Kaiser for pointing me to the logging information that I should have been using in the first place. Now that I have separate log files and debugging information, I'm still at a loss to see why the mail is not being pulled over from the Linux system to the Windows 7 machine. To recap, here is the output from doveconf -n:

---

# 2.2.18: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.8 (0c4ae064f307+) # OS: Linux 4.2.0-27-generic x86_64 Ubuntu 15.10 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no info_log_path = /var/log/dovecot.info log_path = /var/log/dovecot mail_debug = yes mail_location = mbox:~/lib/Mail:INBOX=/var/mail/%u passdb { driver = pam } protocols = imap pop3 ssl_cert =

Here is the configuration logging/debug info:

---

log_path = /var/log/dovecot info_log_path = /var/log/dovecot.info auth_verbose = yes auth_debug = yes mail_debug = yes verbose_ssl = yes

And here is the complete set of Debug/Info information logged when Outlook on the Win7 system attempts a Send/Receive operation. Long lines broken for readability:

Hi

For me it seems like outlook problem (we sometimes get strange problems with outlook, most of the time they are caused either by AV software interfering or outlook user profile or .pst file corruption) Have you checked different mail program or even telnet to see for problems? As or anti virus programs we had problems i can say for sure Norton and Kaspersky were problematic, causing unexpected connection failures ie after successfull auth connection was closed. As for outlook problems in most cases of pst coruption we got outlook errors suggesting connection problems. With profile corruption there were quite fiew different problems (outlook not cnnecting, droping connection out of bue, having problem authenticating, repetadly asking for password ...) The best way we found to test it was using different emai client to test if the problem is generic or outlook related in rare cases we used telnet (pop3 is quite simple protocol)

As for dovecot side there are some compatibility options for older (hopefully) mail clients outlook related would be pop3_client_workarounds = outlook-no-nuls oe-ns-eoh

As for Your log last line suggests there are 3 mails in inbox

Info: Disconnected: Logged out top=0/0, retr=0/0, del=0/3, size=36928

top=x/y x- top commands issued (comand to retrive part of message ie headers) y - bytes sent as result retr=x/y x - retr commands issued (client requests to get message) the size is cumulative size of all messages del=x/y x - number of deleted messages y- numer of messages in inbox before any deletes, if there were no deletes total messages in inbox size=x - mailbox size in bytes before any messages were deleted

mbox format stores multiple messages in single file You can just du sudo -u sherril cat /var/mail/sherril to see the messages on commandline and at same time check if user sherril has permission to read the file (if im right you are using system users not virual ones) but according to the log everything should be ok.

regards Przemek

There are no errors. We have a pop3 connection. The user's name, uid, gid, password, home directory are all correct. The inbox is listed as /var/mail/sherril which is correct, and this file has the correct ownership and permissions:

# ls -l /var/mail/sherril -rw-rw---- 1 sherril mail 194900 Feb 11 09:00 /var/mail/sherril

Yet, no mail is pulled over. Are there any clues here?

Thanks,

Jeff

Examples using openssl s_client:

openssl s_client -connect server_ip:143 -starttls imap

a login username password b list "" * c select INBOX d fetch 1:* flags e fetch 1:* INTERNALDATE f fetch 1:* (body[header.fields (from to subject date)]) g logout

openssl s_client -connect server_ip:110 -starttls pop3

user username pass password list retr 1 quit

I'm just getting around to reading all the helpful messages regarding my problem and will be trying out each of the suggestions. A very big thanks to everyone for the supportive help. I'll let you know what I discover.

In the meantime I wanted to mention one additional thing. I am switching mail over from a Solaris server to a newer Linux box and Outlook on this Windows 7 machine has and continues to successfully communicate with the Solaris system, downloading all the mail. I can take the mail file from the Linux /var/mail directory, transfer it over to the Solaris machine, point the Windows machine at that server, and it downloads the mail without a problem, so if Outlook is part of the trouble, it is due to some unique interaction with dovecot. All file permissions and ownership are identical on both servers. So there is some subtle issue here that I just haven't nailed down.

Regards,

Jeff
