Horde and Attachments

[Snapdragon]

Greets

I cannot say if this is a 7.5.2 problem or not.

All my clients have problems attaching documents bigger than about 5K after a while.

If I reboot the server, I can send a 1.5 Mb attachment, no problem. But after a day or so, it will just hang up.

I have checked the other threads, done the smtp -> sendmail change and back again, checked all the php.ini max limits and execution, memory limits, etc.

Nothing works.

Even before I made all those changes, a reboot would solve it. A courier-imap restart doesn't fix it either.

Any suggestions? I just did another reboot and now it's working fine again.... for now.

Also I will mention that in the horde.log I am getting the error line for line 931, can't send data.. but not always.. just some times..
