Hello Martin, sorry for taking a while to answer ... could you retest with 1.12.5 (current playstore version)? Do the imap server processes never go away? Is the Android client stably connected to network or dropping on and off? In the latter case it is the job of the imap server to drop the connections because the app has been killed and has no knowledge anymore of the connection itself. thanks for bringing this to our attention -- it could hint to a problem but it's not clear there is one on DC's side yet. Also we didn't hear of this problem and many people have limits on number of IMAP-connections. Btw IMAP is only used for receiving messages. Mails are sent out via SMTP which is an independent protocol. holger On Sun, Oct 11, 2020 at 18:13 +0200, Martin Stenzel wrote: > Dear members of the list, > > > by chance I found out, that DC does not disconnect from the IMAP server. > > > My configuration > > > DeltaChat client (Linux & Android) latest version (1.12.0). > > IMAP-Server Dovecot latest version (2.3.11.3). > > > I have a few processes who should not be there - all linked to Deltachat > activity: > > m.stenz+  8486  7550  0 18:57 ?        00:00:00 dovecot/imap > m.stenz+  8488  7550  0 18:57 ?        00:00:00 dovecot/imap > m.stenz+  8490  7550  0 18:57 ?        00:00:00 dovecot/imap > m.stenz+  9288  7550  0 18:59 ?        00:00:00 dovecot/imap > m.stenz+  9289  7550  0 18:59 ?        00:00:00 dovecot/imap > m.stenz+  9290  7550  0 18:59 ?        00:00:00 dovecot/imap > m.stenz+ 11162  7550  0 19:02 ?        00:00:00 dovecot/imap > m.stenz+ 12221  7550  0 19:05 ?        00:00:00 dovecot/imap > m.stenz+ 12229  7550  0 19:05 ?        00:00:00 dovecot/imap > m.stenz+ 12238  7550  0 19:05 ?        00:00:00 dovecot/imap > m.stenz+ 14286  7550  0 19:10 ?        00:00:00 dovecot/imap > > > If I understand correctly, once a message is sent via the DC client and > processed by the IMAP server there should not be a process running any > longer. > > I do not think this is a dovecot problem. > > If there are too many processes from one client IP dovecot will stop > process further messages (max. default is 10). > > > Martin. > > > > -- > Find PGP public key here <https://www.xy-space.de/m.stenzel@mail.xy-space.de.asc> > > > > > __________ Information from ESET Mail Security, version of virus signature database 22135 (20201011) __________ > > The message was checked by ESET Mail Security. > http://www.eset.com > > _______________________________________________ > delta mailing list -- delta(a)codespeak.net > To unsubscribe send an email to delta-leave(a)codespeak.net
