After I've configured dovecot for SSL according to the info given
in the link below:
https://access.redhat.com/kb/docs/DOC-6671
(tried both POP3 & secure POP3 & got the same result)
I tested POP3 access from my unblocked (no firewall rule for outgoing)
broadband PC's Outlook to connect to the postfix/dovecot server & got
the following :
Tasks Status
===================== ========
Establish network connection Completed
Find outgoing mail server (SMTP) Completed
Find incoming mail server (POP3) Completed
Log onto incoming mail server (PO...
Send test e-mail message Completed (yep, this email
was
received in postfix mailbox)
& seconds later, the following messages returned:
Log onto incoming mail server (POP3): The specified server was found,
but there was no
response from the server. Please verify that the port and SSL
information is correct. To
access these settings close this dialog, then click More Settings and
click on the Advanced
tab.
Find incoming mail server (POP3): Outlook could not connect to the
incoming mail server
(POP3). The problem could be the server name or port, or your server
may not support
SSL. Verify your port and SSL settings in More Settings under the Advanced tab.
Q1:
What do I need to provide to this list for further troubleshooting?
Q2:
I have the following log entry in /var/log/mailog :
Mar 31 10:48:36 hostname postfix/smtpd[22258]: warning:
smtpd_sasl_auth_enable is true, but SASL support is not compiled in
Is this related to my POP3 connection issue?
Q3:
Is the following related to the sasl issue in Q2 & the POP3
connection issue ?
[root at host /etc/sysconfig]# saslauthd -v <== expectg postfix to be
listed below
saslauthd 2.1.19
authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap
[root at host /etc/sysconfig]# rpm -qa | grep -i sasl

cyrus-sasl-gssapi-2.1.19-5.EL4
warning: only V3 signatures can be verified, skipping V4 signature
cyrus-sasl-sql-2.1.19-5.EL4
The above cyrus/sasl rpms are old existing packages that were already
there in the server a couple of years ago & well before I installed postfix
& dovecot in this server. Wondering if they interfere with postfix sasl
authentication.
There's no issue with this postfix+dovecot box sending &
receiving emails.
