I have my own email server and I've recently noticed that many of the emails I sent ended up in the recipients' spam folder. I have verified the IP of my mail server and it's not in any blacklist. What could be causing this? Could it be that my IP doesn't have a long history? How can I fix this?

I recommend the MXToolBox SuperTool:
To check if your IP is on any blacklist, enter the command:
blacklist:IP
To check if your IP has a reverse DNS record, enter the command:
ptr:IP
To check if your IP has a forward-confirmed reverse DNS, enter the command:
a:hostname
where hostname if the result of the second check. It should return your IP.
Other things you can try to pass common spam filters (like Google's):

and after all get content-analyzer on recipient side, which consider text as spam anyway – Lazy Badger – 2012-03-04T08:56:31.423
Long history? Is the IP a static address? – Paul – 2012-03-04T03:25:40.197
2Don't send spam, maybe? At last, it's recipient's side solution, you have to ask other side, not blindly find non-existent answer – Lazy Badger – 2012-03-04T08:58:38.443
Ask one of the recipients to forward you a mail that went to Spam. Then check the mail headers for possible information why it went to Spam. – Der Hochstapler – 2012-03-04T13:45:54.823
