Convert Sieve filter from SquirrelMail

[achekalin]

RainLoop version 1.12.1, Dovecot 2.0.9, OS: CentOS 7.5

As we tried to move out of old SquirrelMail webmail, I find we can not edit Sieve filters that was made in SquirrelMail. The IMAP server is dovecot, storage is Maildir, and what I can see, RainLoop can not see or edit SquirrelMail's filters (and vise versa).

First of all, it uses different files to store filters: phpscript.sieve vs rainloop.user.sieve. They are slightly different from each other, like this:

SquirrelMail's phpscript.sieve:

# This script has been automatically generated by avelsieve
# (Sieve Mail Filters Plugin for Squirrelmail)
# Warning: If you edit this manually, then the changes will not 
# be reflected in the users' front-end!
#AVELSIEVE_VERSIONYTo0OntzOjU6Im1ham9yIjtpOjE7czo1OiJtaW5vciI7aTo5O3M6NzoicmVsZWFzZSI7aTo5O3M6Njoic3RyaW5nIjtzOjU6IjEuOS45Ijt9
#AVELSIEVE_CREATED1514299391
#AVELSIEVE_MODIFIED1514299391

require ["fileinto","imap4flags","vacation"];
# rule:[zabbix@domain.com]
if allof (address :contains "from" zabbix@domain.com", header :contains "to" "me@domain.com")
{
        fileinto "FromZabbix";
        stop;
}

while

RainLoop's rainloop.user.sieve:

require ["fileinto"];

# This is RainLoop Webmail sieve script.
# Please don't change anything here.
# RAINLOOP:SIEVE

if header :contains ["From"] "zabbix@domain.com"
{
    fileinto "FromZabbix";
    stop;
}

/* END:FILTER */

I'd be more that happy if I can set it up to use the same file and same format, but even if it is not possible, I want to do once-only SquirrelMail -> RainLoop filter formats, so I can convert it and use RainLoop further.

Thank you!

This problem has been reported before and while it is inconvenient, the (manage)sieve implementation is IMHO at fault here. As far as I know RainLoop cannot "read" the current rules set by another webmail because there is no way of reading it via managesieve.

And while you now have phpscript.sieve and rainloop.user.sieve there is only one of those active in ~/.dovecot.sieve or whatever file you configured in Dovecot.

For my site I instructed all users to migrate their old settings to the new where applicable. Sad but true.
