July 14, 2020 Conference Call Summary 

Updates On Persona Sending Bugs In 8.8.15 Patch 11 
In last week’s call ( [ http://forums.zimbra.com/viewtopic.php?f=9&t=68486 | http://forums.zimbra.com/viewtopic.php?f=9&t=68486 ] ), Noah P. reported 3 bugs related to sending email with a Persona from the Zimbra Web Client, following the installation of 8.8.15 Patch 11. Noah described the first bug last week as: 

Bug # 1.) From the Web Client, sending an email from a Persona account results in the email being sent to the recipient, however the email remains in the Drafts folder and does not appear in the Sent folder. This occurs when the Persona address is the primary address of another mailbox account, but does not occur when the Persona address used belongs to a distribution list or alias address. 

Noah said that Zimbra Support has acknowledged this as a bug and assigned ZBUG-1670. He commented that this bug appears when the “zimbraAllowAnyFromAddress” setting is enabled ( [ https://wiki.zimbra.com/wiki/Prevent_Sending_Email_on_Behalf_of_Someone_Else | https://wiki.zimbra.com/wiki/Prevent_Sending_Email_on_Behalf_of_Someone_Else ] ), but it does not appear to occur if the Zimbra “sendAs” or “sendAsDistList” (for distribution lists) settings are used instead ( [ https://wiki.zimbra.com/wiki/SendAs_sendOnBehalfOf | https://wiki.zimbra.com/wiki/SendAs_sendOnBehalfOf ] ). John H. said the only time that the “zimbraAllowAnyFromAddress” setting should be needed, is if sending from an email address that is not hosted on the local Zimbra server. In comparison, “sendAs” is used for allowing users to send from an email address on the local Zimbra server. 

The second Persona bug described last week was: 

Bug # 2.) From the Web Client, if sending an email from a Persona account that is the primary address of another mailbox account and which also has a status of Lockout, the message will not send and returns an error of “account.ACCOUNT_INACTIVE”. Manually changing the status of the account from Lockout to Active works around this bug. 

Noah said that Zimbra Support has acknowledged this as a bug and assigned ZBUG-1665. The third Persona bug described last week was: 

Bug # 3.) From the Web Client, if sending an email from a Persona with an inline image in the signature, the message will not send and returns an error of “service.PERM_DENIED”. If the inline image is deleted, bug # 1 described above may still occur. This bug does not occur if the signature image is attached, instead of inline, and likewise does not occur if the inline image is included as part of a reply message. 

Noah said that Zimbra Support has acknowledged this as a bug and assigned ZBUG-1666. Mark S. commented that he recommends to his customers to edit the source code of email signatures, so that images in signatures can be referenced to a public web server hosting the images, rather than the Zimbra Briefcase, to avoid permission errors. 

Blank BCC Field On iOS Devices 
Noah P. reported that in 8.8.15 Patch 11, with Exchange ActiveSync 16.1 enabled, that his customers are reporting that they are seeing blank BCC fields when reading any email message on their iOS devices, even when the sender of the messages did not specify a BCC address. This issue does not appear if the iOS devices are configured to use IMAP. Cine suggested setting up a MobileNG account logger (“zxsuite mobile doAddAccountLogger” with either the debug or trace level) to capture what is going wrong with the iOS devices. Noah said he opened Zimbra Support case # 01027536 for further investigation. 

Repeated Full Synchronizations On iOS Devices 
Mark S. reported that in 8.8.15 Patch 10, when an iOS device requests a full synchronization using Exchange ActiveSync, the Zimbra server responds with the folder list, followed by the iOS device repeatedly restarting the full synchronization again. Cine asked if the customer’s iOS device is setup to synchronize tasks, and Mark confirmed task synchronization is disabled. Cine recalled a prior support case where task synchronization caused a similar issue. Mark said he opened a Zimbra support case for further investigation. 

Update On Disappearing Or Incorrect Calendar Events On iOS Devices 
In the June 30th Zeta Alliance call ( [ http://forums.zimbra.com/viewtopic.php?f=9&t=68342 | http://forums.zimbra.com/viewtopic.php?f=9&t=68342 ] ), Gary C. reported that his customers were complaining of events unexpectedly disappearing from their calendars, or appearing on incorrect days/times on their iOS devices while running 8.8.15 Patch 10. Gary reported that after upgrading to Patch 11, in addition to upgrading the affected customers to Exchange ActiveSync version 16.1, as recommended by others in the June 30th call, the problem has continued. Cine suggested initiating a full re-synchronization of the affected devices, either from the Zimbra Administration console (Network Modules NG > Mobile), or by removing and re-creating the Exchange accounts on the iOS devices to force a full re-synchronization. 

False Spam Positives 
Gary C. reported an issue from a customer where senders on the customer’s approved list were mistakenly being delivered to the Junk folder in Zimbra, rather than the Inbox, as expected. He had the customer provide the full email headers of the affected messages, and the headers correctly reference the senders as being recognized by Zimbra as on the approved list. John H. suggested checking the Preferences > Trusted Addresses setting in the Zimbra Web Client, which will allow a sender’s message to skip the spam checks. Mark S. explained that this is different from a similar sounding setting found at Preferences > Mail > Spam Mail Options, which might be the cause of the issue. 

Open Source Binaries Of Zimbra 9 Now Available From Zextras 
Cine shared that unofficial Zimbra 9 FOSS binaries are available for download at: [ https://www.zextras.com/zimbra-9/ | https://www.zextras.com/zimbra-9/ ] 

Canceled Zimbra Cloud Webinar 
Randy L. shared a reminder from Synacor that the Zimbra Cloud webinar scheduled for Wednesday, July 15th was canceled and is postponed for a later date. 

Disabling Redo Logs In Zimbra 
Noah P. asked if the Zimbra redo log (/opt/zimbra/redolog) is still needed since the Zextras NG backup feature no longer relies on them, and if they can be disabled. John H. said that if the legacy Zimbra backup is not being used, then the redo log is likely not needed. David M. said the last time he did a Zimbra install, he recalled having to manually set the option to auto delete rolled over redo logs. He asked if that is still the case on a new Zimbra install for either 8.8.15 or 9.0. Mark S. said that he noticed that the installer still defaults to enabling the legacy backups. Cine said that when a Smart Scan backup runs, it checks if auto roll over for redo logs is off, and if so, then the Zimbra administrator should get an email notification. Chad A. commented that he already disabled the redo logs to save on CPU and disk I/O since switching to using NG backups.
