There could be any number of reasons. Here are two:
1. How are you sending mail? Is each message generated individually, or are
you "bulking" them, using the bcc: field? Anti-spam software targets this
and often blocks mail sent this way.
2. Could you be in a blocked set of IP addresses? We generate emails every
evening from ExpertHost.ca; at one time a spammer used one of their
servers. A specific customer complained that he never received news of the
next day's bulletin. Checking with his IT dept, and ExpertHost, led to the
discovery about the spam, and the blocking his IT dept had put in place.
The end user can also be the problem, depending on how the anti-spam
software is set up. Maybe the very frequency of mail from the same address
triggers the block.
Is a complete and useful set of headers generated in the email? Do other
Yahoo accounts receive your email? Have you talked to the local ISP?
This isn't much help, but the problem is a social one, not a PHP one.
