I had this problem also! Worked fine with 5.0.12, I tested beta1 and 2 and seemd to work fine also, but with POP of my customer domain I had ALL .pdf cut! That was going to be a disaster for me.
I had to use fetchmail instead of "external account", that fortunatly was working fine, even if less than optimal ("Get mail" does not fetch as you press it, he has to wait until cron executes fetchmail).
Messages i.e. of 240K and a pdf attach were fetched by zimbra only for 235K, resulting in a corrupted pdf. With .doc, .ptt or .jpg I had no troubles.
I'm going to file a bug about that.
So seems that grabbing mail from POP in 6.beta does not work with all POP servers, don't know why (pop.tiscali.it works, pop.mycustomer_at_register.it not). |
