I'm using Mail Software to send out emails. My problem is that all mails I send out is carrying a SPAM tag on the subject line even if I didn't put any. However, if I send using squirrel-webmail, my subject line is exactly correct - no spam tags. I haven't changed any settings in my Mail Software. What could be the issue here? Hope you guys can help. Thanks a bunch!
It is probably done by your ISP. For some reason, its mail program is tagging your messages as spam. Are you sending out messages to multiple recipients, or with empty subjects? Check also your mail settings, see if your name, email address, etc are correct.
