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@host /etc/sysconfig]# saslauthd -v <== expectg postfix to be listed below saslauthd 2.1.19 authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap
[root@host /etc/sysconfig]# rpm -qa | grep -i sasl cyrus-sasl-md5-2.1.19-5.EL4 cyrus-sasl-devel-2.1.19-5.EL4 cyrus-sasl-ntlm-2.1.19-5.EL4 cyrus-sasl-2.1.19-5.EL4 cyrus-sasl-plain-2.1.19-5.EL4 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.
