Hello,
I keep seeing a large number of seg faults on some connections when doing a
"verify=csa" in an acl.
Mar 14 11:02:32 kernel: [404922.048624] exim[7892]: segfault at 55a883cd3000
ip 000055a881b84746 sp 00007ffd6e48b730 error 4 in
exim-4.92[55a881b48000+102000]
While running in full debug mode, it looks like it is something to do with
the dns lookup getting redirected with a CNAME?
11:02:32 7892 check verify = csa
11:02:32 7892 CSA lookup of smtp407.td3x.com
11:02:32 7892 DNS lookup of _client._smtp.smtp407.td3x.com (SRV) succeeded
11:02:32 7892 CNAME found: change to td3x.com
11:02:32 7788 child 7892 ended: status=0x8b
11:02:32 7788 signal exit, signal 11 (core dumped)
11:02:32 7788 0 SMTP accept processes now running
> set type=srv

Server: 127.0.0.1
Address: 127.0.0.1#53
Non-authoritative answer:
_client._smtp.smtp407.td3x.com canonical name = td3x.com.
Turning off "verify=csa", these clients work fine on retry (I wasn't
actually doing much with the csa result other than logging).
Best wishes,
Michael
