[SOLVED] warning for attachement size

[forstera]

Good morning,
We've a support department that must receive big files as attachements. I already increased the max attachement size according to a previous post (increasing the zimbraFileUploadMaxSize and the zimbraMtaMaxMessageSize) to allow 30 MB attachements but still can't received an attachement of 13 MB.
Then, if the message can't be received, is is possible that the support mailbox receive a warning message that says that a mail coming from x has not been delivered due to a too big attachment ?
Thanks a lot for your help and thanks for your great software

I'm assuming 31,457,280 is the size you used for 30MB's.

I had to set my server to 15MB to receive 10MB files. Not sure if there is overhead or what. I would be interested to see how big you have to set the parameters to receive the size of file you are trying to receive. Keep upping it till it works then let me know, please.

Did you check max message size as well as max attachment size? You could allow attachments the size of the moon, but if the message size is capped they still won't go thru.

There is definitely overhead. Try attaching a file of known size (say 1 or 2 MB to an email and then take a look at the size of the email. This is the overhead of doing email encoding. See this thread for a detailed discussion.

So, I changed the 2 parameters zimbraFileUploadMaxSize and zimbraMtaMaxMessageSize to allow 30 MB message size. Then I tried to send an Email with an attachment of 16 MB. I checked it with uudeview and the effective size was 19 MB. But zimbra refused the email saying that it was too big. I'm going to change the 2 parameters with 50 MB and going to try again.

Best Regards

P.S Is there a way to configure zimbra to warn the owner of the mailbox when a message is refused due to its size ?

Thanks for your help
Regards

Those sizes should be adequate for sending a 16MB attachment, the overhead for conversion is round about 30%. Which version of Zimbra is this? Are there any more messages in the logs around the time you try to send an email+attachment? Do any attachments get through? What type of attachments are you trying to send?

Working fine now, the problem didn't come from Zimbra but from my firewall that did not allow big emails (above 12 MB). I changed this option and it's working now.
Sorry for this wrong request

Those pesky firewalls--can't live with 'em, can't live without 'em!

Glad to hear things are OK, marking this thread "solved."
