[SOLVED] 8.8.11.GA Intermittent client error, "Zimbra IMAP4rev1 server closing connection"

[pgzimbra]

This issue was originailly opened for ZCS 8.8.6 at

viewtopic.php?f=15&t=63835

where the discussion died with no resolution.

It's still occurring running:

Code: Select all

zmcontrol -v
  Release 8.8.11.GA.3737.UBUNTU16.64 UBUNTU16_64 FOSS edition, Patch 8.8.11_P3.

With Thunderbird v60.6.0/Linux client, I intermittently (I can't yet reproduce these on-demand ...) see:

"The current operation on 'Inbox' did not succeed. The mail server for account user@example.com responded: mx.example.com Zimbra IMAP4rev1 server closing connection."

Did anyone get this resolved? Or has the discussion moved to another topic/thread?

For anyone interested, switching IMAP servers to Dovecot or Cyrus solves the problem.

Hello,

may I ? This is not a solution but a workaround

call it whatever you like.

my goal is to not have the problem for clients.

this is a longstanding, unresolved issue with zimbra', that's not getting acknowledged/addressed.

lacking any alternative, the 'workaround' of getting rid of zimbra works.
