Dear all,
I today saw three bounces where the receiving mail server had said:
host mail.gfbv.de[185.199.217.16] said: 550 external MTA sending our header From: XXXX <XXX@gfbv.de> (in reply to end of DATA command)
The SPF record for gfbv.de is
gfbv.de. 86400 IN TXT "v=spf1 mx a:epicmail1.newsaktuell.net ~all"
I am not sure, whether mailman 2 has any workaround for this like for the DMARC issue
Can anyone spot, whether there is something wrong with the SPF record? Whose fault is it?
My mailman instance has its own spf record:
lists.ilo169.de. 9531 IN TXT "v=spf1 mx a ip4:5.9.62.175 ~all"
I am not familiar with the spf syntax, so I can't tell whether it is our fault or theirs.
At first glace, it would look to me as if the solution would be similar to the DMARC workaround, that is to swap the original From: address with the list address. But again, mailman offers this option only for DMARC issues.
Does anyone have advice for me?
Thanks so much in advance,
Johannes
