similar to: iPhone/iPad IMAP connection bursts causes user+IP exceeded

Thanks for the reply and suggestion Robert. I have now set mail_max_userip_connections to 400 in 20-imap.conf to see if it makes any difference. Late yesterday the customer tested from his office, an older IOS 9 tablet and he had IMAP working in a matter of minutes, so is certainly an newer software version by Apple issue.

Apologies for bumping Joseph Tam's rather old thread, but I'm wondering if anyone has come up with a workaround/fix for this problem that iOS Mail.app clients (10.3.3, 11.0.3, 11.1?) continue to exhibit?

Wow excellent feedback Joseph, Philon and Aki, You have all pointed me in the right direction. Tonight I have tested Dovecot with just the minor configs I do for Dovecot setup and I have commented out the mbox/Maildir lines in 10-mail.conf from my testing: #mail_location = #mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u #mail_location = maildir:~/Maildir I had run up some test files

Thanks for the reply MJ. Good to hear it works in MailDir format - might need to look at this. To date I have only had this issue with Outlook and for me personally on Fedora with Thunderbird, I tend to keep a heap of e-mail folders without sub-foldering and have my own little Linux 'utopia' of annually archiving folders etc using the Linux scripting environment, so I never have

Hi David, I somehow remember that there is a way to get the mail_location from per-user-settings. I had this once when migrating from maildir to mdbox. You might want to use Google and the mailing list archives for the details but in summary it went like this: - set Dovecot to grab the mail_location from user-settings (I think we used MySQL db field - or check docs for auto:) - have login

Hi All, please be kind, this is my first e-mail to the list :-) I actively support CentOS based e-mail servers running Dovecot, Sendmail, Spammassassin and 3 x SOGo based setups. Dovecot is my goto IMAP server and have used it and modifications to it to net excellent results for years. Then we have people who insist on only using Outlook (and in some instances the MS Live Messenger thingy).

Hello everybody, I am in the process to install dovecot as an IMAP server. Currently, this system runs postfix and uses procmail for local (mbox style) delivery. Procmail ist started by postfix like this: /etc/postfix/main.cf: mailbox_command = /usr/bin/procmail ~/.forward: "|IFS=' ' && exec /usr/bin/procmail -f- || exit 75 # jw" Before going

After setting imap_hibernate_timeout to 60s, I could not find any hibernated connections after a few hours. I tested hibernation and made an observation: IDLE'd imap sessions only hibernate if they don't have a mailbox SELECT'd, otherwise they never hibernate. Is this the way it's supposed to work?

Hi Mike, I haven't seen your messages come through the feed so something is not working for your e-mail address there? No I am not using Sieve - the server has a third party handling spam etc so the Linux box is very basic SendMail, Dovecot and RoundCube setup (along with my own procmail based web interface for e-mail forwarding and away message responses). I struggle on. On 09/10/17

Hi All, After over a week of stuffing around in /etc/dovecot/conf.d files and lots of trial and error, I now have a controlled setup to migrate one user at a time to Maildir without affecting the other mbox based users. For the sake of not posting an essay, if you go to this web page: http://dmc1961.id.au/howto_17101101.php you will see what I have done (moderators please let me know if this

Hi Josef, Just went through this one recently using CentOS with SendMail, Procmail and IMAP conversion from mbox to Maildir - I needed to make sure I could run both formats while I migrated users one-by-one. Not sure if what I did helps, but I created a 'how-to' page on it on my website rather than post an essay on the e-mail forum: http://dmc1961.id.au/howto_17101101.php In essence

Hi All, Thanks to MJ for the suggestion as my only hope, and I have tested this with Outlook 2016 and Thunderbird today - seamless creation of folders. Now the mammoth task of converting customers with masses of mbox folders to MailDir format using the on-line perl script: mb2md-3.20.pl Works nicely and will be what gets us out of trouble. My only sadness is that Outlook then has to be

Hi All, This is my first post so forgive me if this hits the wrong list. I have been using dovecot for years happily with SendMail on mainly CentOS servers, and my customers are starting to more and more use Thunderbird, so my perfect model is: Linux --> Dovecot --> SendMail --> Thunderbird (or mobile phone e-mail app). I do have some customers using Outlook or Windows Live Mail,

Hello, I just recently switched my system from a BincIMAP/vpopmail to a Dovecot/vpopmail system, and I have to say: thanks! There were really only two things I had to patch Dovecot to do: first, provide statistics on network usage, and second, to allow folders to be LIST'd/SELECT'd/etc. with a trailing separator (to satisfy my pine users). If anyone's interested, I can generate a

Yes Eric, Outlook also has a declaration that as of either version 2010 or 2013, they no longer download IMAP headers, they download the whole message - thank God for faster Internet connections these days - could you imagine that in the older dialup days? Still it is a waste of bandwidth and disk space to do this. I am so tired of how they claim to use the RFC and indicate they are

Hello all, I'm wanting to set up IMAP bandwidth monitoring, but I don't see any IMAP size transfer entries in the log file. How would I turn this on? Please refer me to the manual if I've somehow missed it :) Thanks, Phillip

W/o downtime: see the wiki page below, the "Converting" section. Briefly for my case something like this should work and generally seems simple (no syntax checking yet, pseudo-code like): * Configuration uses mail_location = mbox:~/mails * setup per-user mail location and do for each user individually in a serial manner: -- doveadm sync maildir:~/Maildir; mbox is synced to Maildir,

Hi, I am not an professional system admin, but I am running a small debian mail server for many years. It is time to migrate from mbox to Maildir. There is a nice and clean description for doing this without service downtime at https://wiki.dovecot.org/Tools/Doveadm/Sync I have to set per-user config for mailbox type using userdb extra fields. However, I miss some information and I can not
