smtp_auth vs relaylock

[NakedIron]

For some reason under the
relaying / authorization is required settings... if I have both POP and SMTP active, users cannot use smtp authentication in their client software.

If I turn off the POP setting, then authentication works again.

Has anyone else been experiencing this problem?

I had the same problem after upgrade to 8.4.0. Fixed it by checking "Only use of full POP3/IMAP mail accounts names is allowed". I was able to turn SMTP back on as well as requiring authorization. Your users will have to change their User Name in whatever email program to include their domain they are using but it seems to be a valid work around until this is fixed.

I had these problem once.I think it depends on the type of email client connecting, take for instance outlook. you will have to enable "Log on to incoming mail server before sending mail"
