This task is about removing the following code from production mail servers controlled by SRE:
```
92 # Aliases for OTRS queues. Do NOT place OTRS queues here!
93 wikimania: wikimania-info
94 # rerouting these for the fundraiser to not overload OTRS
95 #donation: info-en
96 #donations: info-en
97 #donate: info-en
98 donation: fundraising
99 donate: fundraising
100 donations: fundraising
101 otrs: otrs@ticket.wikimedia.org
```
It is a subtask of T122144 and also T297307. at T297307#7574106 and T297307#7574634 it was discussed to move these over to ITS as a follow-up.
Originally this was supposed to happen in 2016 in T128647 but we did not end up doing it until today because of T128647#2087287.
I added the "wikimania" and "otrs" ones because they are kind of in the same section and all of them originally related to OTRS (now VRTS)
