Hi,

Firstly hope I have the right forum as I am a system administrator of the company I work for.

We have a new installation of Zimbra 8.0.2 on a CentOS6_64 install.

We have previously had Zimbra running successfully but never with ZCO, always using either web portal and/or iMap in Thunderbird client. There error is as follows:

"
Error: This message could not be sent.

Subject: Specials

Error Code: 413

None of these images are large in size and we are unable to find the source of this problem...

From what we can find there should be no issue here but we have limited knowledge regarding this and how to trouble shoot this error.

All help is appreciated,
Regards,
