Hello Stephen. Thanks for going public again, in the end this is about the software.

Thanks. Well ... to me this looks like a server error for now. In the meantime i have had a short glance at RFC 4954, and it seems to me 334 is not even continuable, not to talk about doing "334 " twice, it then really should be "334-" plus "334 ". Funnily just today a new sendmail appeared, 8.17.1!! https://ftp.sendmail.org/sendmail.8.17.1.tar.gz That does not help you of course :( 'Was just looking, 8.15 was current from 2015-07-03 until 2020-07-05 ... However, many seem to have patched it in between. Sorry, Stephen, but that error does not seem to be on the S-nail side; and it really only ever offers GSSAPI? That noone else ever encountered that? Well tomorrow i could look into Alpine, if you say that this does NOT fail? Just wondering... Ciao and good night from Germany, Stephen. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)
