On my Gemini (official SFOS X) SMTP connections to strato.de don't work. Jolla C / Jolla Tablet don't have this problem. I readed the accounts serveral times (with reboot between delete/add). IMAP with the same username/passwort works with no problem. Other accounts - for example GMX - working without a problem on the gemini.

Example messageserver log:

Does somebody have an idea? :(

<login hidden> do you happen to supply only a login name or also a domain\login name. It looks like the HELO response is quite late for the EHLO message.

The server doesn't like your computer name (see HELO "[fe80::7f1c:9e91:8e04:70b2%ifb0]"), and responds with "501 5.0.0 Invalid HELO domain name"

Don't know which e-mail program you use and/or whether the HELO name can be configured, but you will have to check that, or contact strato.de to tell me to allow your name. Can't say right now whether the name should be allowed though, as it seems to be a non-routable IPv6 address, instead of your public one (the one mentioned by the server in reply to the HELO).

Good luck.

i use the default sfos mail program on the gemini. how can i alter the hostname mail communicates with the smtp ?

The HELO/EHLO name should be a FQDN, which ideally should resolve back and forward to the IP you are using to connect to the server.

However the server should not reject messages based on that, which strato.de is apparently doing. see RF2821, section 4.1.4: " The SMTP client MUST, if possible, ensure that the domain parameter to the EHLO command is a valid principal host name (not a CNAME or MX name) for its host. If this is not possible (e.g., when the client's address is dynamically assigned and the client does not have an obvious name), an address literal SHOULD be substituted for the domain name and supplemental information provided that will assist in identifying the client.

An SMTP server MAY verify that the domain name parameter in the EHLO command actually corresponds to the IP address of the client. However, the server MUST NOT refuse to accept a message for this reason if the verification fails: the information about verification failure is for logging and tracing only. "

I have no experience with the SFOS mail program. If it's using the hostname, it should be fine (my Jolla1 replies the domain name, hostname -i produces the (local) IP). But I have no clue why your mail program sends an invalid EHLO "[fe80::7f1c:9e91:8e04:70b2%ifb0]" (the "%ifb0" should not be there).

You should try with a better server (gmail, if you have an account there, will give you better diagnostics).

Add.: why the Sailfish mail program sends "AUTH CRAM-MD5" when the server has replied with 501 failure is a mystery to me (and a bug..)

So you might want to use a better e-mail program too.
