Postfix errors in Logwatch

[Marc Schwartz]

Hi all,

Over the past couple of weeks or so, I have noted new error messages in
Logwatch pertaining to Postfix. I use Postfix and Dovecot to support an
IMAP configuration for the local delivery of root's e-mail to my user
account, with Thunderbird as the client. These messages had not appeared
previously and I cannot at this point, recall any changes that I have
made or recent RPM updates that may have triggered this. The e-mail
delivery does work, so whatever is happening, it is not precluding basic
functionality.


The error messages (a subset) follows:

 **Unmatched Entries**
        1   Oct  5 21:38:28 WALL-E postfix/smtp[7960]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 13:28:28 WALL-E postfix/smtp[19392]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 21:38:28 WALL-E postfix/smtp[7961]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 20:28:28 WALL-E postfix/smtp[5056]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 16:58:28 WALL-E postfix/smtp[28624]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 22:48:28 WALL-E postfix/smtp[10868]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 22:48:28 WALL-E postfix/smtp[10867]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 08:48:28 WALL-E postfix/smtp[6426]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
        1   Oct  5 16:58:28 WALL-E postfix/smtp[28626]: connect to ghost.localhost.com[10.11.12.13]:25: Connection timed out
...


Note that the errors are not in chronological sequence and there are
lots of them. Also, I can find no reference to ghost.localhost.com or
the IP address in any of the Postfix or Dovecot config files. A Google
search showed some references to ghost.localhost.com, but nothing
appeared to be relevant to this particular situation relative to
solutions.

Any ideas? Anything jump out from the above?

TIA,

Marc Schwartz
