parameter 'from' contains an invalid email address

Hi,

i’ve got some messages in log:

SyncObject->Check(): object from type SyncMail: parameter 'from' contains an invalid email address '"=?utf-8?Q?=22Groener_St=C3=BCckgut=22_=3C=227323962115=22=40faxmaker=2Ecom=3E?=@domain.de" <=?utf-8?Q?=22Groener_St=C3=BCckgut=22_=3C=227323962115=22=40faxmaker=2Ecom=3E?=@domain.de>'. Address is removed.

utf-8 compatibility-check? (“St=C3=BCckgut” should display “Stückgut”)

("@domain.de" -> my domain)

Same error (invalid address) i get with our mailing-lists:

SyncObject->Check(): object from type SyncMail: parameter 'from' contains an invalid email address 'Verteiler IT'. Address is removed.

I can use the Lists, but everytime this warning appears.

The Lists are located at “CN=Verteiler IT,OU=eMail-Verteiler,DC=domain,DC=de”

since its not really effecting daily work, its more the type of “good to know”.

Have the same issue with the removed address. There are similar errrors in the log for the from field.
This occurs in Core 8.4.0-728
The from field is okay in Core 8.4.0-415. But the to is not always okay and produces the same error.

I use z-push 2.3.6 on Ubuntu 16.04 64-Bit with PHP-FPM 7.0

https://jira.kopano.io/browse/KC-709 was created by @fbartels to research this issue and others.

@Coffee_is_life said in parameter 'from' contains an invalid email address:

=22Groener_St=C3=BCckgut=22_=3C=227323962115=22=40faxmaker=2Ecom=3E?=

The email is quoted printable encoded and should have been decoded on receiving the email via kopano-dagent.

Then still, even decoding it correctly it becomes

"Groener Stückgut" <"7323962115"@faxmaker.com>@domain.de

which isn’t a valid email address.

About the “Verteiler IT” - looks like a group. The issue here is that is doesn 't seem to have an email address at all, probably related to KC-709 as mentioned already.

@Sebastian said in parameter 'from' contains an invalid email address:

probably related to KC-709 as mentioned alread

but only if you are running 8.4.0, but you signature suggests otherwise.

Indeed, KC-709 shouldn’t be present in 8.2.1.

  1. Do you receive these emails regularly? We would need the raw RFC822 received by the dagent on delivery. You could enable log_raw_message in your dagent config and when receiving such a mail identify the email and send it to support.

  2. Not sure about this, but I would say make sure your groups also have email addresses or that they are expanded on sending.

kopano-admin -V
Product version:        8,2,1,531
File version:           531

“Verteiler IT” is a distribution-group in ad. Sure it has no mail-address because its just to contain users of the same department. If i send to “Verteiler IT” and expand this before sending - sure no error.

I will generate a log via special_user_logging, and provide you both, the log and the mail :)
