First, make sure you have the mail log on a backup

You can also make a copy and have it save to another temporary location and then backup from that location:

For example:

cp -p /var/adm/syslog/mail.log   /file_system_that_has_enough_space

To clear the log after making sure you have it on a backup or have made a temporary copy do this:

cat /dev/null > /var/adm/syslog/mail.log

That will empty out the log

A large mail.log file usually indicates something is wrong.

Have you read any of the messages? Are the messages coming in every day?
If so, I would fix the problem(s) first, then copy the old mail.log file to an archive location.
Then use compress or gzip t compress the old file. It will be reduced to about 1/10 original size.
