List, good evening,
We use Fetchmail to collect email from various addresses and
providers. The incoming mail is passed to Exim for delivery to
mailboxes, and served to local MUAs on the network using IMAP provided
by Dovecot. We've had this architecture in place since Debian Etch
(D4) and it is (still) working well. We are updating our network to
run those same applications on a new box with Wheezy, and we are
testing this at the moment. For testing purposes, we have set
Fetchmail on both machines (the live Etch system, and the trial Wheezy
system) to 'keep' the POP3 mail on the ISP servers, and not flush the
downloaded mails. This way, we can be sure that both machines will
'see' the same mail, and we can check everything is working on the new
machine. It isn't.
The new Wheezy system uses Fetchmail 6.3.21-4, and we are using the
exact fetchmailrc from the Etch system (Fetchmail 6.3.6-1etch2). The
usernames and passwords are in the fetchmailrc file. One of our POP3
providers is gmx.net, though we do not actively use that address so
much, and the traffic is low. We've noticed that Fetchmail on the new
Wheezy system isn't seeing most of the gmx.net email. This is
because, though it initially connects at each poll, presents the
password, and receives the mail, after a few polls, it seems to fail
the authorisation. (I'm not sure why, yet.) Fetchmail logs the poll
and reports authorisation failure. It never re-establishes
authorisation on successive polls. It does successfully download
mails from gmx.net after this, when I restart Fetchmail:
# /etc/init.d/fetchmail stop
# /etc/init.d/fetchmail start
The live Etch machine is reporting no authorisation problems, and sees
all the gmx.net mail.
I've looked through the man fetchmail pages and I'd like to get some
extra logging but I can't seem to pass the -vv parameter to fetchmail.
Fetchmail starts as a daemon, and I can stop it and start it again, but
# /etc/init.d/fetchmail start -vv
doesn't seem to have any effect.
Is there a way I could restart fetchmail as if it had been invoked as
'fetchmail -vv'? With the extra logging I am hoping it will say why
the authorisation is failing.
Grateful for any advice,
regards, Ron
