Hello everybody,
recently I checked my mail.log and for every mail processed I have two errors there:
milter-greylist: smfi_getsymval failed for {if_addr}
and
milter-greylist: smfi_getsymval failed for {i}
I’m sure this is quite new and I guess it came up when I set a mail limit for a certain domain (100 mails per minute).
Now to my questions:
-
Can I do something against these errors? (I really don’t like errors in my logs )
-
If not are they really safe to ignore like some other threads would suggest, if yes what exactly do they mean?
-
I have my mail setup configured so that SPF and DKIM is checked as well, does the milter greylist interact/interfere with with this in any way or can I assume DKIM and SPF checking still works like it should? (I ask because errors make me worry that maybe there are some cases were mail relaying would fail which really wouldn’t be good.)
-
If milter greylist is only used for mail rate limiting like stated in another thread, can I disable it (and thus hopefully get rid of the errors) and is there maybe an alternative way to limit mail rates?
Thanks a lot for clearing this up!
