Can I erase my Mail logs

What do you mean by "100 gb of mail logs". You mean the emails? How did you figure the size was 100gb. ( some of the system reports are inaccurate. )

The mail app stores the mail ~/Library/Mail. What type of account do you have? exchanage, imap or pop?

I do a full backup of your system. I'd proceed with caution. You never know what might happen. You don't want you bosses coming by your office. If it aren't broken don't fix it. Just get a larger disc.

Maybe someone else can explain it.

(1) You might want to run

Run

OmniDiskSweeper

"The simple, fast way to save disk space"

(2) You could try the unix disk utilization command. du

# I think unix still uses 1024 for k instead of 1000 for k

/Applications/Utilities/Terminal

Unix navigation commands.

I didn't realize they could be so big.

Yes you are safe to delete all those .txt file logs—

From the Finder>Go>Go To Folder, copy&paste:

~/Library/Containers/com.apple.mail/Data/Library/Logs/Mail 

I have seen anywhere from 12 GB to 342 GB of logs built up here.

Don't forget to empty your Trash.

Use these logs only when trying to troubleshoot a problem.

You can turn off Mail logs. Mail.app>Window>Connection Doctor> uncheck Log activity.
