Topic: Folders are created due to the sender

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 1.5.0
- Linux/BSD distribution name and version: Centos 7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): 3433692 Emails. 65.87 GB.
- Web server (Apache or Nginx): Nginx
====

Hi Friens!

The problem lies in the following. When the sender indicates my mail and adds "+", then a new folder is automatically created on the server in which this letter is located.

For example, my mail is: support@megapr.com
and they send me an email to support+0dd9e@megapr.com

as a result, the folder 0dd9e appears in which the letter lies.

How to make sure that folders on the server are not automatically created using special characters, often spam mailings began to be done according to this principle.

Re: Folders are created due to the sender

Find these lines in /etc/postfix/master.cf:

# Use dovecot's `deliver` program as LDA.
dovecot unix    -       n       n       -       -      pipe
    flags=DRh user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain} -m ${extension}

Remove the ending " -m ${extension}", restart postfix service.
