Not really solved, but resolved I guess as far as it's not an issue any more, I ended up using my secondary backup B3 unit. Just made sure I had copied data over and swapped out the devices.

I am going to wipe and rebuild the problem unit, I had full backups of everything so just swapped the units ...

Hello Chaps.

It's been a long time since I've been here! My B3 has been running fine with no issues, and little need for interference for pretty much 2 years, other than general maintenance.

Anyway, this week I hit an issue and I think it was due to the recent vulnerability that I've seen here ...

Ok so after my 5TH call to my mail host they finally admit that they had blocked my IP Address - not sure why they hadn't realised before then but that has just cost me 1 full day's email activity due to their incompetence!!

Thanks for the suggestions guys.

SOLVED

Hi Thanks for the replies.

I've tested the login's manually and they work fine, and I've also checked with the ISP and I've not been blocked (That was my first thought)

It's set to check every 3 mins.

I've just changed the usernames on some of the accounts to be:

name@domain.co.uk

Instead of ...

Ok, so have dug through the Mail Log some more and found where is starting going wrong:

Apr 6 08:53:39 main-bubba fetchmail[1100]: Server certificate verification error: self signed certificate
Apr 6 08:53:39 main-bubba fetchmail[1100]: This means that the root signing certificate (issued for /C ...

Hi Guys,

Been running a B3 now for a few months and have it happily handling email for about 10 accounts via POP3 download. Then clients logging on via Thunderbird and collecting email by IMAP.

However, came in this morning and for some reason, the B3 is failing to pickup emails from my mail host ...

Yes, I have not removed the folders - thought I'd leave them as it's only my account which has been affected since I was the only account logged in before changing Mailbox locations.

All other accounts are working fine an no logging errors since AFP has been disabled.

I've updated the dovecot.conf file similar to yours,

The only part that was missing was:

mail_location = maildir:~/Mail
mail_privileged_group = mail

I've added this in and now the mails are in the folders as they should be, there are some extra folders in the list:

Inbox (17/25)
.Account ...

Ok, so have opened up the dovecot.conf file and found that under protocols there was nothing after the =

So I edited it to be:

protocols = imap imaps

And now I can log onto the webmail interface, it's not the same as it was before, the folder list is a mess but at least I am logged in.

I think ...

Ok, so have now removed those log files, rebooted with those lines in the dovecot.conf file and have disabled netatalk.

I've opened those dovecot log files and this is what is printed:

root@main-bubba:/tmp# ls
dovecot-info.log dovecot.log ftdaemon sess_7bnf8o9akfqcl65b6nfbfq3oj0
root@main-bubba ...

There is a Mac machine on the network running Windows 7?

I didn't think this was related to the dovecot, I have a feeling the dovecot issue can be resolved by geting the space back on the partition and then making sure my dovecot.conf file is configured properly.

I will try disabling netatalk - if ...

Ok, so the following 2 logs, Daemon, Syslog are 4GB each and both contain the following line over and over:

Nov 29 15:17:35 main-bubba cnid_metad[1148]: error in select: Bad file descriptor

Am researching it now.

my /var/log directory is 8.8GB!!!

Just checked it - just trying to find out what is causing it, then will do a reboot.

Sorry, I thought I included the output of df -h it is:

root@main-bubba:/home/main-user# df -h

Ok, so I checked to see if the new certs had been created, and there is a dovecot.pem

Point 2) I was unable to find anything relating to an error from dovecot, only what I've posted before (I can check logs if you know of any)

I was going to edit the dovecot.conf file but I checked the login and ...
