I am running a webserver hosting two domains (domain1, domain2). Further, I am using iRedmail as the mailserver. I can receive emails for both domains, however, when I try to send a mail from either of the two domains, the mail lands in the SPAM folder when the receiver address is a hotmail address but not when the receiver address is from Google.

I have the following DNS-Entries for the two domains:

For Domain1:

mail.domain1    86400   A   0   THE-IP
domain1         86400   A   0   THE-IP
domain1         86400   MX  10  mail.domain1
domain1         86400   TXT 0   v=spf1 a mx a:mail-relay.contabo.net include:_spf.google.com ~all 

For Domain2:

mail.domain2    86400   A   0   THE-IP
domain2         86400   A   0   THE-IP
domain2         86400   MX  10  mail.domain2
domain2         86400   TXT 0   v=spf1 a mx a:mail-relay.contabo.net include:_spf.google.com ~all 

What am I missing?

New domains have at least a 6 month warming period before they start hitting the inbox in Hotmail. You might be able to accelerate that, by having your IP's mitigated via through a ticket with Microsoft sender support. You also need to have everything else set up correctly on your domain.

Take a look at this Email Deliverability Guide

Here's the form for Microsoft Mitigation to full out: Microsoft Sender Support

You're SPF looks fine for a redacted version.
