Application Development Software

Hallo

As I see, I have common problem among the Sun Messaging Server administrators. I have whole system distributed on several virtual solaris machines and some days ago emerged message size problem. I noticed it in relation with incoming mail. When I create new user, he or she can't get larger mail then 300K. Sender get will known message:

This message is larger than the current system limit or the recipient's mailbox is full. Create a shorter message body or remove attachments and try sending it again.
<server.domain.com #5.3.4 smtp;552 5.3.4 a message size of 302 kilobytes exceeds the size limit of 300 kilobytes computed for this transaction>

Interesting thin is, that this problem arised with no correlation with other actions. I noticed this problem with new users before, but i could successful manage it with different service packs. Now this method with new users, this method doesn't work! Old users normally recieve messages bigger then 300k, as before.

I tried to set default setting blocklimit 2000 in imta.cnf, but I didn't succeed.

I know, that size limit can be set on different places, but is there a simple way, to set sending and recieving message size unlimited?

Messaging server version is:

Sun Java(tm) System Messaging Server 7u2-7.02 64bit (built Apr 16 2009)*
libimta.so 7u2-7.02 64bit (built 03:03:02, Apr 16 2009)*
Using /opt/sun/comms/messaging64/config/imta.cnf (compiled)*
SunOS mailstore 5.10 Generic_138888-01 sun4v sparc SUNW,SPARC-Enterprise-T5120*
