z-push and faulty headers

[HansMeiser]

Hello,

iam having an issue which seems not to be directly a bug of z-push, but its affected by faulty header created by other Applications.
Z-Push logs:
06/27/12 14:50:04 [7847] [myusername] IMAP-errors: Unexpected characters at end of address: <>
Correspondig Part in Mailheader seems to be:
From: "example@example.com" <>

There is no address between the <> in From Line, z-push stops syncing, imap-server itself has no problem with this.
I informed webmaster of sending system and telled that they create faulty headers but may be it is also a good idea to add a kind of fix in z-push to avoid errors caused by other Applications.

Thanks,
Hans

Hi Hans,

I can't find any piece of code in Z-Push which outputs "IMAP-errors:", only in kolab.php. Which Z-Push version are you using? Can you post more of the log?

Greets, Manfred

Hello,

i can locate it in backend/imap.php line 92: foreach ($errors as $e) debugLog("IMAP-errors: $e");

this is full significant part:

Hi Hans,

yes, indeed. However this error is from the IMAP extension for PHP, there is nothing we can do about it. I think your problem is rather the line above:

IMAP-errors: Connection failed to localhost,143: Connection refused

You should check your imap server's log.

Were these 2 messages retrieved by your mobile?

Hello,

this line is always shown at every new Mail arrives. Maillog is ok, no Problem logging in.

Code: Select all

Jun 28 16:40:23 myhost dovecot: imap-login: Login: user=<myusername>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS
Jun 28 16:40:23 myhost dovecot: IMAP(myusername): Disconnected: Logged out bytes=305/11564

Iam surprised that message "connections refused" always occurs after sucessfully login and syncing mails:
