[veto]

i'm just in a the process  of migrating a froxlor managed couriermail server to a new froxlor/debian9/postfix/dovecot mail server

there are hundreds of gigabyte imapmap emails with hundreds of accounts.

to make this a bit less painfully to move

i started to created a small email migration script for the beginning

https://github.com/veto64/sync_froxlor

 

requirements:

emails passwords must be plain

latest docker

remote access to the server

is there any better way to prevent spamming.? there is a virus poping out in my system called vigrx plus what is the solution

 

[d00p]

dovecot is not there to prevent spam...if you need virus/malware removal, google for a solution or hire a good admin

1) Create a bash script to receive e-mail from Postfix and pipe it to SpamAssassin for rewriting. Then forward the rewritten version to Postfix's sendmail implementation:

#!/bin/bash
#
# spamfilter.sh
#
# Simple filter to plug SpamAssassin into the Postfix MTA
#
# Modified by Jeremy Morton
#
# This script should probably live at /usr/bin/spamfilter.sh
# ... and have 'chown root:root' and 'chmod 755' applied to it.
#
# For use with:
#     Postfix 20010228 or later
#     SpamAssassin 2.42 or later

# Note: Modify the file locations to suit your particular
#       server and installation of SpamAssassin.
# File locations:
# (CHANGE AS REQUIRED TO SUIT YOUR SERVER)
SENDMAIL=/usr/sbin/sendmail
SPAMASSASSIN=/usr/bin/spamc

logger <<<"Spam filter piping to SpamAssassin, then to: $SENDMAIL $@"
${SPAMASSASSIN} | ${SENDMAIL} "$@"

exit $?

2) Ensure the newly-created /usr/bin/spamfilter.sh has correct permissions (0755), and is owned by root:root.

3) Modify the /etc/postfix/master.cf file; first, change the first 'smtp' line of the file to:

smtp      inet  n       -       -       -       -       smtpd -o content_filter=spamfilter

Then, add the following (a call to our newly-created spamfilter script) at the end:

spamfilter
          unix  -       n       n       -       -       pipe
   flags=Rq user=spamd argv=/usr/bin/spamfilter.sh -oi -f ${sender} ${recipient}

Have a look at http://www.scrolloutf1.co I use two of these as mx0 & mx1. They are reliable and fairly easy to get up and running.

You would need to set them up with sticky records, then point your domain name(s) MX records  to use these. From within Scrollout you then forward the email that is permitted to your Froxlor server.

You can utilize a variety of techniques to transfer mailboxes from an IMAP server to an Office 365 server. However, I prefer EdbMails IMAP to Office 365 Software, which is specifically intended to function in many domains and allows customers to easily migrate IMAP to Office 365/Exchange server. 

The application is compatible with all IMAP email servers, including Google Mail - Gmail, Outlook.com, Office365.com, Yahoo Mail, Yahoo Mail Plus, Yahoo Mail UK, Yahoo Mail, and others. It may be used by both technical and non-technical users. The program is well-designed, with some wonderful capabilities that allow you to transfer all of your IMAP emails to Office365 with ease compared to other competitors.
