Easy solution: use port 465 (instead of 587 + STARTTLS). It's faster and you don't have to EHLO twice to start up the connection.
Sorry to say, however switching to port 465 doesn't make any change. Tried it right away, however did not work. Just lacking some feedback and logging information. Will do ASAP
Well that's odd. I've been using port 587 (and more recently 465) to relay from mobile and desktop clients for literally decades. It has always worked for me in Haraka and it still does.
Thanks for the tip of changing to 465. We had the same problem this year with clients sending mail from dynamic IPs in Sweden and Germany, using port 587. Users were not able to send because of DNSBL "spam" class for their IP, even though they authenticated. Sometimes I myself could not send from mobile. I guess it could maybe be a result of more IPs listed on some DNSBLs. After changing to 465 I have not had the problem. For the users using 587 we raised the karma limit for haraka, which ended user complaints, but I guess also will let more spam through. Thanks again.
Yes, in karma.ini I raised the AUTH score, and also lowered the "negative" threshold:
[result_awards]
#162 = auth | pass | match | auth | 18 | Authentication success
162 = auth | pass | match | auth | 50 | Authentication success
[thresholds]
; negative: the threshold below which a connection is denied/rejected
; Be conservative to avoid false positives!
#negative=-8
negative=-18
Describe the bug Sending a mail from mobile is blocked due to dnsbl.
To Reproduce Send mail from smartphone on the AT&T / Vodafone network in Netherlands. When I'm connected to the mobile network and try to send a mail this blocked due to the mail is seen as coming from dnsbl. I did check the IP : 109.38.148.204 which is indeed listed at zen.spamhaus.org. However cannot really influence which IP I get from my mobile provider..
Expected behavior Authenticated users should somehow be able to send mail, since they cannot really influence the IP they are send from.
Maybe it is more Haraka, please let me know if I should place it there.
