Postifx mail receiving size limit

[t_ras]

using kubuntu 9.04 on AMD 64,working with ISPconfig panel
I have postfix configured and have no problem getting mails with small attachments, but when they pass certain size I don't get them
Where can I configure this?

Are you using a webmail in php ?
If yes, you have to modify the php.ini file and increase the size limit.

But if not, I don't think modifying the php conf file will helps...

If you've got webmin installed, the relevant page is servers->postfix->general resource control. There's an option, "max size of a message"

It seems to work from other accounts, it seems the problem was in the source account.
sorry for waisting your time...
